Ovulation Calculator

Sandra asks…

How do I use the ovulation calculator if my periods are off?

July 8 and Aug 15 (38 days), Aug 15 and Sep 12 (28 days) Sep 12 and Oct 23 (41 days) Oct 23 and Nov 26 (34 days) Nov 26 and didn’t come on in Dec…. Jan 8 (43 days), Jan 8 and Feb 5 (28 days) Feb 5 and Mar 13 (36 days) No period for April yet… So how do I calculate that?


Pregnancy Advisor’s answers:

Yeah, irregular periods make it difficult to know what’s going on. I wouldn’t recommend using an ovulation calculator to anyone, even someone with “perfect” 28-day cycles. They’re too cookie-cutter and often inaccurate because they assume so many things. I would recommend you try basal body temperature charting, or monitoring your cervical mucus since these things do not depend on cycle length to tell you when you are in your fertile window or when you’ve ovulated. Also, once you’ve ovulated you can count the number of days between ovulation and the first day of your period. The number should always be pretty close to the same, and that way you’ll know when you’re late. Usually it’s between 10-16 days, and it’s known as your luteal phase length. The actual day of ovulation can change from month to month, for example one month you could ovulate on day 13 of your cycle and the next month you might ovulate on day 15, so the only constant thing in your cycle that you can depend on is your luteal phase length. When you’re counting luteal phase length, just remember that the first day of your period counts as the first day of the new cycle. So to answer your question, I really don’t think there is any way for you (or anyone) to use an ovulation calculator and be able to depend on it. Maybe you could try using ovulation predictor kits, which can get expensive, or you could start basal body temperature charting through somewhere like www.fertilityfriend.com , or maybe you could just google how to check your cervical mucus. I really think using a different method of predicting ovulation will be most beneficial, especially for you since you have such varying cycle lengths. Good luck!

Carol asks…

Website for an ovulation calculator that asks for your last two periods?

The only ones i could find asked for just your last one, and idk how many days are in between my cycle cause it changes. and i need to be POSITIVE on my fertile days cause im trying to get pregnant…

Pregnancy Advisor’s answers:

I believe its webmd-they ask for the last 3 cycles

Ruth asks…

Ovulation calculator and irregular periods?

I wanted to use an ovulation calendar but my period is irregular. It asks how long my cycle is and I’m not sure how many days. My last period cycle was 31 days while the one before that was only 26. These are the only time I’ve kept track. Am I still able to use the calculator? How?

Pregnancy Advisor’s answers:

I kinda doubt it. You ovulate roughly 14 days BEFORE your next period, but if you have no way of knowing when it’s coming, you basically have no way of knowing when you’re gonna ovulate. Sorry to be the bearer of bad news. My periods are super irregular, like ranging from 19 days once to a 4 month cycle next, if that can be called a cycle. Hubby and I just tried to make sure we had sex every other day the entire time I was off my period (every other day is what is recommended while you are ovulating). That way, you are sure to get some sperm in there when there is an egg. It took us 11 months to get pregnant. Good luck, I know how frustrating it can be.

Donna asks…

How many people have used a Ovulation Calculator?

To judge on when is best to try and conceive, if so has it worked for you? and how long of trying it did it take?
i havent actually used one yet, but am going to now this month, i have looked at a load of them and all but 2 pinpoint my egg relase day as the 26th so i think im gonna take a chance on them and just hope for the best

Pregnancy Advisor’s answers:

They are not terribly reliable, as they are based on the “average” cycle, while your cycle might not be “average.”

I stopped using these and started tracking my BBT, cervical mucous, cervical position and using OPKs. By doing this I found out that I actually ovulate on day 18, which none of the online calendars could have figured out.

Now, I input all that data into FemCal, an iPhone app, and have a great handle on when I am fertile! Hoping it works!!!

Mandy asks…

Where can I find a online Ovulation Calculator for a cycle lasting 100 days or more?

Pregnancy Advisor’s answers:

Try to use this ovulation calendar tool http://www.ovulationcalendarsoftware.com/ to trace your cycle and find the date of ovulation.

Ovulation Calendar Girl

Ruth asks…

Could my girl friend be pregnant? Please help!?

My girl friend is on The pill. She takes it at 9 every night and has never forgotten to take it however she’s been an hour late a couple times and sometimes she’s like 15-30 minutes late taking it. Even though she’s on the pill, I always use a condom.
Is it possible that she could’ve gotten pregnant from a little bit of pre ejaculation?
We tried sex without a condom for about 10 seconds and realized it was a dumb idea. I ejaculated the day before but pissed probably at least 5 times after the previous nights ejaculation.
I don’t know how much I could’ve pre-ejaculated but in the 10 secondsor so we were having sex, I know I could’ve..
Her ovulation date was last week. She figured it out with an ovulation calendar.
What do you think? I know it’s “possible” but is it likely.. Or like, what’re the chances that the pre ejaculation got her pregnant???

Additional details:
I know for sure I didn’t have any “spurts” of actual sperm or anything like that go in her, all I’m worried about is the pre-ejaculatle stuff…

please help!!

Pregnancy Advisor’s answers:

First point, a timing difference of upto 1 hour is acceptable while taking the pill. So no problem due to that.
Second, birth control pill has a success rate of upto 98-99%, which is very good.
Now about pre-ejaculate stuff, this liquid is called pre-cum, and yes it may contain sperm though chances are very less. So if pre-cum contains sperm, it can make her pregnant.

Mary asks…

How can the day you have sex determine the sex of the baby?

I was looking up ovulation calendars and I came across one that told me when to have sex if i wanted a girl and when to have sex if i wanted a boy. I know that it’s the male’s sperm that determines the sex of the baby, but does it also have to do with the day just like this website said??

Pregnancy Advisor’s answers:

It is said that sperm that carry male DNA swim faster than sperm that carry female sperm, but that female sperm live longer once they reach the fallopian tubes. Supposedly if you have sex the day before or of ovulation you will have a boy and if you have sex 2-3 days prior to ovulation you will have a girl but there is no exact evidence of studies that have been done to prove this.

Susan asks…

Conceiving a girl vs. conceiving a boy?

I just checked my probable ovulation dates using this calendar: http://www.freeovulationcalendar.net/ You put in the info, and it gives you a probable ovulation date. But it also says there’s a higher probability of conceiving a girl at the beginning of ovulation, and a boy toward the end of ovulation. Has anyone ever heard of that? That gender depends on when you conceive? Does this sound odd?

Pregnancy Advisor’s answers:

Actually I have heard of this, and it is a little more in depth then that. It is true that timing has some increased chances of one sex or the other but there is never a guarantee that you will get what you are trying for.

Girls are difficult because you have to predict when you will ovulate and you have to try to have intercourse as far before ovulation with out ruining your chances altogether. So you would try 5 days before one month. If it does not work then 4 days before the next month, but never any closer then 2 days before (that is even close) and no unprotected sex the rest of the cycle.

Male sperm swim fast but die off quickly so If the egg has been released the odds of having a boy are high.

Female sperm swim slow but live longer so they will hang around and wait for the egg. (amazing even in sperm form, we have more patience lol).

If you want a boy have intercourse on the day you ovulate.

Also for a girl tighter undies for the guy. For a boy loose. Too tight and the sperm count can be too low.

So I hope that this helps. I was not aware that they were actually putting that on temp. Charts.

Good. Luck.

Lisa asks…

Boy or girl? Can you choose?

I’ve been looking at some ovulation calendars and I’ve noticed they ask if you have a preference on conceiving a boy or girl.

I always thought the sex of the baby was decided by the sperm, not by the day you conceive.

Are these calendars true or is it even possible to choose?

Pregnancy Advisor’s answers:

There has always been old wives tales about “choosing” the gender of your baby. But it’s the sperm that makes the final decision.

Essentially, there are two different types of male sperm. There are the sperm that produce boys, and then there are, obviously, the sperm that will produce girls. The sperm that produce boys tend to swim faster than the sperm that produce girls, and they get to the egg faster. However, these sperm have a shorter lifespan than the sperm that produce girls. The sperm that produce girls swim slower, but they will often last several days longer than the sperm that produce boys.

To try to determine your babies gender, you can time the day of conception. If you are trying to get pregnant with a girl, you should have sex a few days prior to ovulation. Thus, the sperm that would produce a boy will die off before you ovulate, and will not have a chance to fertilize your egg. This will also give those sperm that would produce a girl the opportunity to get to your egg.

If you are trying for a boy, your day of conception needs to be different. To try to have a boy, you will want to have sex during the time that you are ovulating. Some people have even suggested that you put the day of conception off until the very end of ovulation, although this, obviously, creates a higher risk of not becoming pregnant at all.

Ultimately, the day of conception will not guarantee a babies gender, but it may be able to help.

Does this help?

Maria asks…

i wanna know if my girl is pregnant ?

she got her period on the 31 of DEC and on the 14 and 15 of Jan we had unprotected sex. She had pain in her ovary on the 17 and she was feeling hot. today she had cramps and was dizzy and Nassau. she also released a clear mucus. she supposed to get her next period on the 31 but she never felt like this before. i look up an ovulation calendar and it said she was ovulating on the 17 she can she be pregnant? Thanx
Thank for the response. she also been feeling blooded. we been trying for 4 month and she never felt like this untill know so im happy but don’t want to be cuz i realy don’t know..

Pregnancy Advisor’s answers:

OK the dates that you gave will show that it is possible. But, unless she is really intuned to her body, it is not possible to tell yet. It takes about a week for the egg to burrow into the uteras. And then it has to attatch itself to it. And then start to feed. It has only been 3 days. There are some people that can tell right when the egg is fertlized. Mabe she is one of them. But the only way that you can really tell is to wait until she misses her AF. When/if she misses it, take a test. Because if she was to test right now, the test would not be able to be correct. The HCG levels are not high enough as of right now. Good luck and baby dust to you both.

Lh Surge But No Ovulation Clomid

Mandy asks…

Clomid Sucess Rates and should I get my hopes up?

Just wondering my doctor is just about to start me on Clomid in a few months. I have ready all the books and I am losing weight, stopped drinking caffine, And also quite smoking. (Oh by the way I have PCOS) . The doctor is going to have me try for 2 more months to do it natraully and then if that does not work she is going to put me on clomid. I have done everything possible to do it natraully. I have used the ovualtion prediction kits and layed on my back after sex with my hips up. I am starting to get very frustrated becuase nothing seems to be working and I am worried that taking the clomid will not work either. Any more suggestions….. ?
I am 22 with PCOS. I have done everything that has bin asked by my doctor for someone that has PCOS. I just wanted to know if I have missed anything that I shouldbe doing.. Before I go to using Clomid..

Pregnancy Advisor’s answers:

First, ovulation predictor kits are VERY inaccurate for women with PCOS. It detects the LH surge which means you are going to be ovulating (however, women with PCOS have messed up LH levels).

Your best bet at getting pregnant is going to be treating the PCOS the correct way. To do this you should eat a low carb diet, exercise and be on an insulin sensitizing drug, such as metformin. Once you are on metformin, then you can start all the fertility treatments (such as Clomid, injecibles, IUI, IVF, etc). It might be possible to get pregnant with Clomid alone, but your chances will be much higher if you are on metformin.

I recommend seeing a reproductive endocrinologist to oversee your treatment.

The underlying cause of PCOS is insulin resistance (IR). The best treatment for PCOS is going on an insulin sensitizing drug such as metformin (1500-2550mg per day) combined with a low carb diet and exercise. There are a few important things to know:

1. Many women “pass” the test for IR, but still respond positively from the metformin. No one knows exactlly why..my thought is that the test is not a sure fire way of detecting the IR.

2. You must be on a high enough dose of metformin. I’ve heard women complain that their bodies dont start working even though they’ve been on metformin for awhile. Some doctors are hesitant to up the dose past 1500mg…but for some of us it takes more. I don’t respond until my dose is around 2000mg a day.

3. It can take a few months on the correct dose, before your body is regulated.

4. It is important to treat your PCOS even if you are not trying to get pregnant. There are higher risks for many things (high blood pressure, blood clots, diabetes, and many other things) when you have PCOS, but if it is treated properly, then those risks are lowered.

There are TONS of books about PCOS and dieting. There are two that I recommend. Here’s the links at amazon for those (if you’re interested):



I also recommend a couple web sites:



Http://messageboards.ivillage.com/iv-bhp… This one is a great message board where you can ask all your PCOS questions or just chat with the women who are also dealing with PCOS. Good luck.

Lizzie asks…

What is the the normal follicle size?

My Re gave me Clomid CD 5-9 and Metformin 1500mg. I went in today for my CD12 u/s and I only had one follicle that is 10mm. The dr said that I only have a very slim chance of ovulating this month. Can anyone tell me what the normal size should be? I’m a little down cause I really was hoping to ovulate this month. Thanks for any help.

Pregnancy Advisor’s answers:

I’m sorry…I know how frustrating it is to not ovulate!!!! I think the follicles are typically 22-24mm to stimulate the LH surge and cause ovulation. But follicles that are 14-15mm are also able to be considered “mature” when doing IVF so maybe some sort of stimulation could be used in future cycles? Here’s a good article that might help, http://www.medscape.com/viewarticle/501803, Good luck!!!

Carol asks…

What length cycle do you have when your on CLOMID? 28day 25days etc etc. . . .?

Does it give you a normal 28day cycle? & when on clomid do you ovulate on the 14th day!?

Thanks so much

Pregnancy Advisor’s answers:

Every woman is different.. And no it does not necessarily give you a 28 day cycle. I’ve been taking clomid for the past 4 months.. And my cycles are usually about 32 days. Every woman is also different to when they ovulate. You need to get yourself an Ovulation Predictor Kit (i recommend the Clear Blue Easy Digital) it is a little pricey.. But it is better than the others b/c it tells you for sure and your never guessing. This will tell you when you have ur LH surge, and when you get that + OPK test then you should ovulate withing 12-36 hours.. So… Baby dance every other day from day 10 on.. And ur covered… If you get ur AF then you know ur not prego.. If not.. Then take a HPT.. Good luck!!

Sharon asks…

getting 10 days of high readings on CBE fertility monitor?

I’m on my 3rd cycle using the Clear Blue Easy fertility monitor and have found it very easy to use. This month however, I’m already at 10 ‘high’ days. Last month was 8 and the first month was only 6. Why is this happening?

Pregnancy Advisor’s answers:

It sounds like your body is constantly gearing up for ovulation but your LH surge isn’t happening. I would speak to your doctor and ask him to check your progesterone and estrogen levels to make sure that you are actually ovulating and if not get some medication to help with ovulation like clomid or femara.

Betty asks…

What is a Mid-Cycle Ultrasound? Are they checking for follicles?

I have an appointment with my RE this friday for a mid-cycle ultrasound. I thought it was to check for follicles. I looked up mid-cycle ultrasound and it was saying it is for measuring the endometrial linning. Is that all that is being checked? Or are the follciles being checked then too?

Please let me know your experiences!!!!

Pregnancy Advisor’s answers:

Yes, they check the thickness of the lining and also to see that the lining has 3 layers.
They measure the number and size of the follicles as well. Basically, they want to see how well you are responding to clomid but they also want to make sure your ovaries are not being overstimulated. They also check your LH to see if you are surging. If you have enough mature follicles, they may advise you to use an hcg trigger shot, like ovidrel, to encourage ovulation and to give your early luteal progesterone a boost. They will also measure your estrogen levels to make sure you are not being hyperstimulated.

Ovulation Signs Cramps

Sharon asks…

Cramps after Ovulation..Sign of pregnancy?

Ok so ever since i ovulated i keep getting cramps in my lower stomach..like pinches..my period is not do till another week and its been a week that ive been feeling this..could it be a sign of pregnancy?
My AF is not due until the 28th or so.
What deos 2ww mean?

Pregnancy Advisor’s answers:

Sometimes these pains are a sign of early pregnancy. I am feeling the same pains myself and i am not due until the 30th, so I know what you’re going through and feeling. I just try not to think about it too much, or i end up getting myself overly worked up and then i think i might be making the symptoms up because i want it so bad… To be a mother!

Baby dust to you!!!

Helen asks…

What day past ovulation should you feel cramps if you were in fact pregnant?

i know cramps is sometimes a sign of pregnancy, but does anyone know what day past ovulation(if you were to get pregnant) do you have these cramps? They are similar to menstral cramps right?

Pregnancy Advisor’s answers:

I got cramps abt a week before my period was due (it never came because I was pregnant). It varies for everyone, though.

Lizzie asks…

What are some physical signs of ovulation vs. physical signs of when you’re about to start your period?

Cramps? Tender breasts? Secretions? WHAT? Lol What are signs you are ovulating, what are signs you are about to start your period?

Pregnancy Advisor’s answers:

One physical sign of ovulation is a thick, clear discharge (looks like uncooked egg whites). Our bodies produce it to help the little sperm get to where they are going easier. We ovulate about 14 days after the first day of your past period. Your next period is not due for another 2 weeks after you ovulate. So the main difference between the 2 (in terms of physical signs) in timing.

Mary asks…

Is cramps after ovulation normal or sign of preg. ?

Ive been having cramps for few days after ovulation and some creamy cm too, is this normal? or can i be preggy? thx

Pregnancy Advisor’s answers:

Both If you feel premenstrual just crampy then probably its just ovulation, if you are feel other symptoms of pregnancy then you could be pregnant but I’m willing to bet that its just ovulation.

Maria asks…

Is it normal to have signs of pregnancy between ovulation and your period and not be pregnant?

Okay I have seen tons of posts with people after their ovulation having pregnant symptoms and I wonder if this is just normal and they aren’t pregnant. I am having the same symptoms, temperature, headaches, extreme bloating, ewcm, moodiness, nausea, cramps all day and I am now 5dpo. I am trying not to get my hopes up because I will be crushed if I find out I’m not and I was so sure that I am. So is it normal to have all these signs and not be pregnant? Is it just PMS two weeks in advance?

Pregnancy Advisor’s answers:

Yes, this is normal. In the “TTC” world we call this “IPS” or Imaginary Pregnancy Symptoms. Since you are ttc, you are so much more aware of what is going on in your body. Therefore anything you feel, you attach to pregnancy. This is not to say however, you are not in fact pregnant. You could very well be. But just know that IPS exists.
Hope that helps =)

Lh Hormone Surge And Pregnancy

Mandy asks…

What are the stages before Ovulation and what happens after?

Can anyone tell me what happens when you get ready to ovulate and after ovulation? What occurs afterwards?

Pregnancy Advisor’s answers:

.The First Days of the Menstrual Cycle
The menstrual cycle actually begins with the first day of your period. During this time, estrogen levels in your body are extremely low. This signals your body to produce FSH. As the levels of FSH in your bloodstream rise, approximately 20 follicles inside of your ovary begin to mature. One of these follicles will begin to secrete estradiol, a type of estrogen, while the weaker follicles die off. As your period ends, your body will prepare for ovulation by creating a thicker uterine lining, appropriate for implantation. Your cervical mucus will also change, from thick and clumpy, to thin and slippery.

Ovulation occurs around the 14th day of your menstrual cycle. During this time, estrogen begins to rise rapidly, peaking about a day before ovulation. As your estrogen levels peak, your body will experience a surge in LH, triggering your ovaries to release an egg from its follicle. This egg will enter one of your fallopian tubes and travel towards your uterus. The leftover egg follicle gradually shrinks, becoming the corpus luteum. The corpus luteum secretes progesterone, helping to prepare your uterine lining for pregnancy.

If your egg is not fertilized after ovulation, your body will progress into the menstrual phase of its cycle. During this stage, the unfertilizied egg is expelled from the vagina along with the uterine lining. This is your menstrual period. Typically, menstruation lasts between three and seven days, though it can last as long as ten days. Your menstrual blood may change in color, ranging from bright red to deep brown. You may also notice some small clots in the blood. This is because your menstrual fluid is actually comprised of various cells and tissues. During menstruation, hormone levels drop, signalling the cycle to start all over again.

I googled stages of menstrual cycle. You should too.
Also read the book, taking charge of your fertility. It will educated you beyond what you ever thought you’d know.

Linda asks…

What causes spotting during pregnancy?

Im 9 weeks and had this to happen twice last night and once this morning. It is very faint brownish/pinkish color. I havent had sex in a while so I know it isnt that. It is only when I wipe from using the bathroom. This is my first pregnancy so I am nervous and needing some advice. THANKS

Pregnancy Advisor’s answers:

I am a young physician and I think I may have some insight that may be useful.

During pregnancy, cyclic ovulation and your period do not occur because of several reasons, mostly hormonal. In order for an egg to be let down from the ovary (ovulation) you need a surge of a hormone from the hypothalamus called GnRh (gonadotropin releasing hormone). This surge causes an LH/FSH surge which causes ovulation. Bear with me it gets easier….

During pregnancy this surge does not occur because your progesterone and estrogen levels STAY elevated (during normal non-pregnancy times they go up and down). The high progesterone primes your uterus, causing a nice cushioned bed for the developing embryo (if its intra-uterine, hopefully. And not -intra-fallopian…but that’s a separate discussion).

Some times this cushiony bed of muscles/cells and glands slough off. The shedding of the uterine lining coincides with the spotting you are experiencing. So, little areas of your uterus are shedding its layers which causes spotting during pregnancy. After your mucous plus if formed, most of the spotting is from the cervix.

Pregnant——> elevated progesterone/estrogen——>thick cushioned uterine lining—->(cyclic shedding of this, monthly is called your period) but, during pregnancy only small (hopefully) micro areas, shed and this is what causes mid-term spotting!

Good luck…name him or her Jordan…after me!

Lisa asks…

If I tested positive on OPK but my temp did not rise did I ovulate?

If you test positive on an ovulation kit but your temp does not change what does that mean? And if your temp does change and go up will it stay up if your become pregnant?

Pregnancy Advisor’s answers:

An OPK just shows that you’re surging in LH (luteinizing hormone). This usually happens 24-48 hours before ovulation. Sometimes, our bodies surge, but don’t release an egg. Usually the OPK will drop off for a day or two, and then you’ll surge again, and hopefully ovulate then.

This is possible if you have a hormone imbalance (like with PCOS), but the more likely scenario is that you did ovulation, but your progesterone rises slowly. That means it takes a few days for the rise in temp to show. It’s not a big deal, unless your progesterone is low, which can cause miscarriage. If you notice a slow rise on one or two charts, that’s fine, but if you see a consistent pattern of low temps and bad rises, you should get checked out by a doctor.

If you become pregnant, your temps will stay high, because of the hormones released by pregnancy. However, some fluctuations are perfectly normal. When you get a positive pregnancy test, most women stop charting, just to stop the emotional rollercoaster.

Good luck!

Susan asks…

What hormones are responsible for producing fertile mucus, in the woman, during her fertile phase?

Pregnancy Advisor’s answers:

1. Pre-Ovulatory Hormones – Discussing Estrogen, FSH, LH and GnRH 2. Post-Ovulatory Hormones – Discussing Progesterone, hCG and Prolactin 3. Dispelling Day 14 Myth – Detailing the mechanics of ovulation.

Pre-Ovulatory Hormones – Estrogen, FSH, GnRH, LH
The female reproductive cycle is completely run by hormones. Without the hormones, conception would not occur. It’s no wonder that if any of the key hormones are out of whack then infertility is the result. Maintaining a balance of this fine tuned system of glands and hormone excretions is paramount in the act of conception. It has been said that hormones are the conductor of the body during pregnancy, that hormones run the show, so to speak. Learning about the reproductive hormones can give you a better understanding of what occurs during the cycle month and why you experience certain physical signs as each hormone peaks and drops off in production. These reproductive hormones are released mainly in the pre-ovulatory phase of the cycle, or the first half.


Estrogen is actually a term referring to three separate hormones – estrone, estradiol, and estriol. Because these three hormones are considered the “estrus-producing hormones” it is easier to simply say “estrogen” which refers to the “estrus” class of hormones.

Estrogen is the hormone responsible for the low basal body temperatures in the first half of the cycle. Estrogen prompts the cervix to produce the fertile quality cervical fluid. It controls the entire menstrual cycle. Estrogen levels start off low the first of the cycle and begin to climb as ovulation approaches. It’s the high levels of estrogen that prompt the production of the Luteinizing Hormone (LH).

Luteinizing Hormone (LH)

LH is produced by the pituitary gland. It is released in one surge prior to ovulation, which in fact prompts ovulation to occur. LH levels rise very slowly at the first half of the cycle. When the level of estrogen reaches a high peak it prompts the surge release of LH, known as the LH surge. It’s the LH surge that literally causes the ovary to burst forth the egg.

LH is the hormone detected in ovulation predictor kits. This surge takes place normally 24 hours to 72 hours before ovulation occurs. If infertility is a factor, a woman can have several LH surges in a cycle, thus making the use of ovulation predictor kits more complicated.

Follicle-Stimulating Hormone (FSH)

FSH is produced by the pituitary gland in the first half of the reproductive cycle. FSH is the hormone responsible for prompting the ovaries to produce mature ova or eggs – and the production of estrogen. The levels of FSH are above those of the other reproductive hormones at the beginning of the cycle. Very soon, the levels drop below the levels of the other reproductive hormones. Right before ovulation, FSH peaks, thus causing ovulation itself to happen.

Gonadotropin Releasing Hormone (GnRH)

GnRH is produced by the hypothalamus in the brain. It stimulates the pituitary gland in the production of FSH and lutenizing hormone (LH). This helps in the lead to follicle development and ovulation.

The hormones that run the pre-ovulatory phase of the menstrual cycle are estrogen (estrone, estradiol, and estriol), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and gonadotropin releasing hormone (GnRH). These hormones must work in harmony to bring about ovulation, the release of the egg from the ovary.

Donna asks…

What is the termination of intrauterine pregnancy?

Pregnancy Advisor’s answers:

Dear mem
Now u can plan your pregnancy as u like and choose your date and time of pregnancy as u like with home check ovulation kit because Home-Check Instant Ovulation Test is designed to detect the surge in Luteinizing Hormone (LH). The body always makes small amounts of LH but prior to ovulation it makes far more. This test device will detect the LH surge which happens in the middle of your menstrual cycle, about 1 -1.5 days before ovulation.
