Using a Fertility Calendar to Predict Ovulation
The calendar method predicts ovulation by looking at a woman’s menstrual history. Ideally, the calendar method should be used in conjunction with other predictive strategies, like observing cervical fluids, changes in the position of the cervix, and BBT charting. Also, the calendar method can be used to determine when a woman should start using ovulation tests – products that detect her LH-Surge.

For a more comprehensive calendar method, consider creating a Fertility Chart: using several predictive methods together to pinpoint your most fertile window for conceiving.

The calendar method is designed to predict general trends based on past menstrual patterns – and is therefore limited in terms of “pinpoint accuracy”. The more regular a woman’s cycle, the more effective the calendar method is – and perceiving ovulation patterns begins to crystallize after a few months of maintaining records.

With the ovulation calendar method, a written record is kept using a calendar to follow the patterns of each cycle. Each cycle begins with the first day of one’s menstrual period and ends with – but does not include – first day of the next (which should be recorded as the first day of the next cycle).

How Chart and Read Your Ovulation Calendar

The day menstrual flow begins is ‘Day One’. Circle this date on the calendar and notate as ‘Day One’. For each following month, circle Day One and continue this for for at least 7-8 months.

Continue maintaining a record of the number of days in each cycle. When bleeding starts, circle the date on your calendar.

To determine the first day you are likely to ovulate, examine your records from previous months, find the shortest cycle, and subtract 18 from the total number of days.

For example, if your shortest cycle is 28 days long, subtract 18 from 28, which leaves 10. Starting with the date you circled (Day One, the first day of your current cycle) count ahead ten days and draw an O (for ‘ovulation’) through that second date. This day will be the date you are most likely to become fertile.

Again, the calendar method of ovulation prediction is best used in concert with other methods discussed in the Fertility Charting section – or with ovulation predictor kits. To look at a comprehensive fertility chart See Also: Creating a Fertility Chart


Five Ways to Tell You’re Ovulating
Trying to figure out when you’re fertile? Here’s how to pin down the days.
During each monthly cycle, healthy couples in their 20s or early 30s who aren’t using birth control have a 20 percent chance of creating a baby. And that’s a surprisingly high percentage considering that you can conceive only around the time of ovulation — a small window of opportunity each month (usually about 12 to 24 hours) during which the egg is viable, or open for the business of fertilization. Doesn’t sound like much of an opening? Consider, then, that sperm are able to live to fertilize for a lot longer than an egg is willing to hang out, anywhere from three to six days. Which means that even if you have sex a few days before ovulation, there may be plenty of sperm still around to greet the egg when it emerges. (And remember: It only takes one sperm to make a baby.) Of course, having sex the day you ovulate would be ideal. After ovulation, that window tends to slam shut till the next cycle. Clearly, knowing when the Big O occurs is key when doing the Baby Dance. Here are five ways to help you pin down the big day.
1. Check the calendar: Ovulation most often occurs halfway through your menstrual cycle — the average cycle lasts 28 days, counting from the first day of one period (day one) to the first day of the next period. But as with everything pregnancy-related, there’s a wide range of normal here (anywhere from 23 to 35 days), and your own cycle may vary slightly from month to month. By keeping a menstrual calendar for a few months, you can get an idea of what’s normal for you. (When you become pregnant, this calendar will come in handy to get a better estimate of your baby’s due date!) If your periods are irregular, you’ll need to be even more alert for other signs of ovulation, so read on.

2. Listen to your body: If you’re like 20 percent of women, your body will send you a memo when it’s ovulating, in the form of a twinge of pain or a series of cramps in your lower abdominal area (usually localized to one side — the side you’re ovulating from). Called mittelschmerz — German for “middle pain” — this monthly reminder of fertility is thought to be the result of the maturation or release of an egg from an ovary. Pay close attention, and you may be more likely to get the message.

3. Chart your temperature: That is, your basal body temperature, or BBT. Taken with a special thermometer (yes, you guessed it, a basal body thermometer), your BBT is the baseline reading you get first thing in the morning, after at least three to five hours of sleep and before you get out of bed, talk, or even sit up. Your BBT changes throughout your cycle as fluctuations in hormone levels occur. During the first half of your cycle, estrogen dominates. During the second half of your cycle (once ovulation has occurred), there is a surge in progesterone. Progesterone increases your body temperature as it gets your uterus ready for a fertilized, implantable egg. Which means that in the first half of the month, your temperature will be lower than it is in the second half of the month, after ovulation. Confused? Here’s the bottom line: Your BBT will reach its lowest point at ovulation and then rise immediately and dramatically (about a half a degree) as soon as ovulation occurs. Keep in mind that charting your BBT for one month will not enable you to predict the day you ovulate but rather give you evidence of ovulation after it has occurred. Charting your BBT over a few months, however, will help you to see a pattern to your cycles, enabling you to predict when ovulation will occur in future months — and when to hop into bed accordingly.

4. Get to know your cervix: Ovulation isn’t an entirely hidden process. As your body senses the hormone shifts that indicate an egg is about to be released from the ovary, it begins to ready itself for the incoming hordes of sperm and give the egg its best chance of getting fertilized. One detectable sign of oncoming ovulation is the position of the cervix itself. During the beginning of a cycle, your cervix — that neck-like passage between your vagina and uterus that has to stretch during birth to accommodate your baby’s head — is low, hard, and closed. But as ovulation approaches, it pulls back up, softens a bit, and opens just a little, to let the sperm through on their way to their target. Some women can easily feel these changes, while others have a tougher time. Check your cervix daily, using one or two fingers, and keep a chart of your observations. The other cervical sign you can watch for is the appearance, increase in quantity, and change in consistency of cervical mucus (the stuff that gets your underwear all sticky). Its more noble purpose is to carry the sperm to the ovum deep inside you.

After your period ends, you’ll have a dry spell, literally; you shouldn’t expect much, if any, cervical mucus. As the cycle proceeds, you’ll notice an increase in the amount of mucus with an often white or cloudy appearance — and if you try to stretch it between your fingers, it’ll break apart. As you get closer to ovulation, this mucus becomes even more copious, but now it’s thinner, clearer, and has a slippery consistency similar to an egg white. If you try to stretch it between your fingers, you’ll be able to pull it into a string a few inches long before it breaks. (How’s that for fun in the bathroom?) This is yet another sign of impending ovulation — as well as a sign that it’s time to get out of the bathroom and get busy in the bedroom. Once ovulation occurs, you may either become dry again or develop a thicker discharge. Put together with cervical position and BBT on a single chart, cervical mucus can be an extremely useful (if slightly messy) tool in pinpointing the day on which you are most likely to ovulate — and it does so in plenty of time for you to do something about it.

5. Buy an ovulation predictor kit: Don’t want to mess around with mucus? You don’t have to these days. Ovulation predictor kits (OPKs) are able to pinpoint your date of ovulation 12 to 24 hours in advance by looking at levels of luteinizing hormone, or LH, which is the last of the hormones to hit its peak before ovulation actually occurs. All you have to do is pee on a stick and wait for the indicator to tell you whether you’re about to ovulate.

Another option is a saliva test, which takes a peek at levels of estrogen in your saliva as ovulation nears. When you’re ovulating, a look at your saliva under the test’s eyepiece will reveal a microscopic pattern that resembles the leaves of a fern plant or frost on a windowpane. Not all women get a good “fern,” but this test, which is reusable, can be cheaper than those sticks you have to pee on. There are also devices that detect the numerous salts (chloride, sodium, potassium) in a woman’s sweat, which change during different times of the month. Called the chloride ion surge, this shift happens even before the estrogen and the LH surge, so these tests give a woman a four-day warning of when she may be ovulating, versus the 12-to-24-hour one that the standard pee-on-a-stick OPKs provide. The key to success in using this latest technology is to make sure to get an accurate baseline of your ion levels (currently, there’s a device on the market that needs to be worn on the wrist for at least six continuous hours to get a proper baseline). No OPK can guarantee that you will get pregnant or that you’re actually ovulating; they can only indicate when ovulation may be occurring. So no matter which device or method you choose, patience and persistence are key! Just don’t forget to put together a candlelit dinner, draw a warm bubble bath, or plan a romantic weekend getaway — whatever it is that puts you and your partner in a baby-making mood.


Sandra asks…

What are my chances of getting pregnant?

Im a 34 year old who has been tacking the pill for near on 20 years ive been trying to get pregnet now for almost a year and have not yet has anyone got any info on long term use of birth controll

Try these tips to help you along.
First you need to start tracking your cycle. Since you just started having AF again, may as well start now, at the beginning. About two or three months should tell you when you normally start. Look online for ‘ovulation calculators’ these are free and usually calculate pretty well. Then buy ovulation predictor strips, about $20 for 20 of them at CVS. Start testing 5 days after your period stops and continue testing every day for ten days. The results/days from the ovulation calculator online will fall somewhere within this ten day period. Also, note when you get the slippery thin clear cervical mucus this is at onset of ovulation. Some women do not get the right mucus to keep sperm alive in the vagina, so if this is you then buy PreSeed. Start having intercourse once a day, the day your predictor strips show your LH surge. The LH surge is what the strips are measuring to show if your about to ovulate. You may get positve test strip results for 1 to 5 days. If you are going to ovulate, it will be within 12-48 hours of your LH surge showing up. So try the O calculators online, the O predictor strips and have sex the day of LH surge and the few days after this will likely be the same as The two days before the O calculator says until two days after. Use preseed, it will keep spermies alive longer, makes the vagina a nonhostile environment. One other tip is to use Instead or Diva cups. You can either insert one directly after intercourse or have him get the semen into the cup and then insert it right away. Get it inside you quick and leave it there up to 12 hours. This places the spermies as close as possible to your cervix and holds em in longer to wait for a dropping egg.
Many women do not get the egg white cervical mucas needed to help spermies survive and move quickly to the cervix. Your fluid can be thinned out by taking over the counter robitussn, the plain kind, look this up online too. Or jus tuse the pre seed for this.
You can track your balsal tempurature too. Look that up onliune to see what you are looking for.
THere is a kit called Conception kit. Very expensive. The things in it are cervical cap, O predictor strips and pre seed.
You can make a kit yourself out of the things I suggested for WAY less money and more usefulness.
My kit is in a large feezer bag. O predictor strips, bottle of Robitussin, individual packs of pre seed, Instead cups, my balsal thermometer, a small calandar and some home pregnancy tests.. Only about $200 less than the conception kit sold online!

Helen asks…

When is the best time to get pregnant?

Pregnancy Advisor’s answers:

The best time to get pregnant is when you are ovulating which occurs 14 days before the first day of your next period. For a fool proof way of figuring out the days you are most fertile go to www.babycenter.com and use their ovulation calculator. It is very helpful. I also suggest getting an ovulation predictor kit because everyones body is different and that is the best way to tell when you are ovulating because it detects the LH surge that occurs about 24-48 hours before ovulation. I hope this helps, good luck!!

Lizzie asks…

What do you think ladies?

ok I took an ovulation test on Friday morning and it was negative, Sat. morning it was positive, Sat night and Sunday morning it was also positve. But by Sunday night it was Negative again. So when do yall think that I ovulated? It is now Tuesday, do you think that I have already ovulated. We had friday and sat and then Monday, last night just incase I hadn’t ovulated yet or maybe those little guys could catch up to the egg. So I guess my question is when do you think that I ovulated, if you think I have yet at all.
I wish that people would just answer my question and ot give me a lesson on ovulating and sperm lifespan and what not. I know all that. I just wanted to know if you thought I had ovulated already or if we should continue to have sex to try and get pregnant.

Pregnancy Advisor’s answers:

It could have been anytime Friday evening thru Sunday afternoon. Every woman is different so your egg could still be hanging on if you ovulated on Sunday afternoon! So have sex sex sex! A great way to know when you are ovulating is to chart it on a calendar and test. Also online there are ovulation calculators online to help. Testing along with the calculators helped me zero in on my LH surge.

I wish you lots of baby dust!!!


Sharon asks…

What should I feel during ovulation? ?

Have any of you ‘felt’ your ovulation take place? I am on day 13 of my cycle and am hoping that my slight cramping and pinching feeling in my lower abdomen could be just that! I’m using the CBEFM and I have been high since day 9…hopefully this could mean something…I hope! I’ve also been on clomid days 5-9. Is there anyway I could already by pregnant? We have been trying for awhile. Any help is greatly appreciated. Thanks! 🙂

Pregnancy Advisor’s answers:

It’s extremely important that you use a clomid calculator when using opk’s because clomid will cause false readings due to the estrogen surges it causes and CBEFM base it’s results on lh and estrogen (that’s why it’s the top of the line opk tester). I only found out my monitor was going off wrong from the clomid because my sonogram was showing I had ovulated when I was still on level 2. I was just able to get rid of it thinking it went bad when I had a nurse (from old RE) inform me that you have to test a few days later when you use clomid. I just hate for anyone to have missed their chance to conceive of this issue.

Yes, if it’s 2″ above pubic bone and slightly off to the side from your midsection then it’s likely it ovulation pain. You need to check your cm (for wet/slippery or stretchy) since you can’t go 100% on your monitor this cycle. If you have fertile cm, you need to bd tonight and tomorrow to catch the egg.

Here’s a clomid calculator. Scroll to bottom of the website then enter the date you started taking clomid. It will tell you when to begin opk testing and when you are likely to ovulated.
