Length Of Lh Surge During Ovulation

Sandra asks…

when is a dogs heat over!?

my female and male dog are seperated right now cause my female went into heat. My male is going CRAZY! he constantly whines when in or out of the house! its driving me nutz! he was fine last week but this week he is out of control going crazy!

I know what everyone is going to say… to get her fixed. I havent because I am looking into finding a new home for her because my relationship is failing and I dont have any options and just cant care for her right now. With work and trying to find an apartment- she is a big dog and needs a backyard. So I didnt get her fixed in case the next owner doesnt want her fixed.

Pregnancy Advisor’s answers:

Sexually mature female dogs will go through a heat cycle once, or more commonly, twice a year. Each cycle consists of four stages:

1. Proestrus: Characterized by swelling of the vulva and release of a bloody vaginal discharge. Sometimes the discharge is milky and other times dark red (or somewhere in between in colour). Between bitches, there is a large variation in the length of proestrus, with an average length of 9 days, and a range of 1 to 17 days. This is the “pre-heat” during which the male is progressively more attracted to the female, but the female still rejects the male. This is a high female hormone (estrogen) stage.

2. Estrus: This phase is often termed standing heat because it is during this stage that the female will receive the male dog. Average length for estrus is 9 days, but again, between dogs there is large variation (range 3 to 21 days). At this point, the discharge may be absent, or perhaps straw coloured. This stage is characterized by an increase in progesterone hormone and an LH (luteinizing hormone) surge that leads to ovulation.

3. Diestrus: At this point, the female usually no longer stands for the male, especially further into the diestrus stage. Vaginal discharge tapers off and the diestrus phase lasts an average of about 60 days. Diestrus begins 6 days after ovulation. Progesterone hormones remain high throughout this phase.

4. Anestrus: This is the resting phase between the active portions of the cycles. It normally lasts about 5 months.

Hopefully that answers all of your questions. If not surely one of the sources that I listed below can help you out.

Pregnancy Advisor’s answers:

What is ovulation?

Ovulation is the release of a single, mature egg from a follicle that developed in the ovary. It usually occurs regularly, around day 14 of a 28-day menstrual cycle. Once released, the egg is capable of being fertilized for 12 to 48 hours before it begins to disintegrate. This is the most fertile period of your cycle: during ovulation your chances of conception are highest.

When does ovulation occur?

Ovulation usually takes place 14 days after the beginning of your menstrual cycle. The time of ovulation within the menstrual cycle is determined by the luteal phase, which is usually 12 to 16 days long. You can calculate the time of ovulation within your cycle by subtracting the length of your luteal phase from the length of your cycle. For example, if your cycle is 28 days long and your luteal phase is 12 days long, the ovulation will occur on day 16 of your cycle (28-12=16). The exact time of ovulation may vary within your cycle, because ovulation can be delayed by a number of factors such as stress, illness, diet, or increased physical activity.

How does ovulation determine my fertile days?

Your fertile period starts about 4-5 days before ovulation, and ends about 24-48 hours after it. This is because sperm can live in your body for approximately 4 to 5 days, and the egg can live for 24 to 48 hours after being released. You are most fertile on the day before and the day of ovulation. Knowing your fertile days can help you increase your chances of getting pregnant, or avoid an unwanted pregnancy. Read Ovulation and Pregnancy and Ovulation and Contraception for more information.

How do I calculate my fertile days using Ovulation Calendar?

Can I feel ovulation?

You may experience lower abdominal discomfort, a slight rise in body temperature, and changes in cervical mucus during ovulation. Prior to ovulation, your cervical mucus is cloudy and thicker, and a few days before ovulation it becomes clear, slippery, and stretchy like raw egg whites. Immediately following ovulation, your body temperature can increase by 0.4 to 1.0 degrees Fahrenheit. About 20% of women feel discomfort or pain in their lower abdomen as the egg leaves the ovary. This condition is known as ‘mittelschmerz’, and it usually lasts from a few minutes to several hours.

What happens in my body during ovulation?

The process of ovulation is triggered by the release of Luteinizing Hormone (LH). The levels of this hormone increase significantly about 1-2 days before ovulation, causing the egg to be released from the ovary (this increase is known as the ‘LH surge’). The egg travels down the fallopian tube towards the uterus. If fertilization does not occur within 24 to 48 hours after ovulation, the egg disintegrates and is expelled with the uterus lining at the start of your next period, usually 12-16 days later. If fertilization occurs, the egg implants itself in the lining of the uterus and begins its growth, resulting in a pregnancy.

Im TTC but i got my period today(feb.10,2008).I think my two sisters got pregnant close to their periods.?

what would be the best time to have sex when ovulation occurs during my period time ? thanks.

Pregnancy Advisor’s answers:

It is physically impossible to ovulate when you are on your period. Regardless of length of cycle, every woman ovulates 14 days prior to her period. It always takes 14 days after ovulation for the period to begin, due to the hormonal changes that need to occur to bring on a period. This doesn’t mean you can’t get pregnant near your expected period, it just means that you ovulated later than normal, and so if you hadn’t conceived your period will be later than expected. The best thing to do is take at home ovulation tests (purchase at any pharmacy) – just a stick you pee on at the same time every day (usually afternoon) and that will detect your LH surge (the hormone that releases the egg) so you will have a better idea of when to try. Depending on how regular your cycle is, you may need to use a lot of these (I have an irregular cycle that averages 40 days, and used 3 boxes the month I finally conceived). Good luck – I know it’s hard to be patient!

Ruth asks…

Clearblue Fertility Monitor – Programmed for 2 Peak & 2 High?

I’ve been reading a lot of the questions/answers regarding the CBF Monitor and I’ve seen this a couple of times – - – that the monitor is programmed to give you two peak days, then two high days and then go back to low. Therefore folks have stated to stop testing after your first peak day. Is this true? Reason I ask is b/c on my day 9 I was low and then day 10 & 11 I was PEAK (with no high days inbetween). Today, day 12, I’m high. Thoughts? Should I stop testing?
And one more question for you – On my first peak day (day 10), my husband & I ‘baby danced’ that night; did not on day 11. Thoughts on that as well?
Sorry for all the questions… Thanks in advance!

The New And Advanced OV-Watch® is worn on the woman’s wrist while she sleeps. Women start wearing OV-Watch® on the 1st, 2nd, or 3rd day of their menstrual cycle and wear it through ovulation. It measures a woman’s changes in her chloride ion levels that are secreted in perspiration every 30 minutes and records up to 12 readings per period.

OVWatch’s patented technology detects the chloride ion surge and alerts the woman to FERTILE DAY 1, FERTILE DAY 2, FERTILE DAY 3, FERTILE DAY 4, OVULATION DAY 1, and the day after. It is the ONLY device of its kind that can give you the 4 days BEFORE ovulation. That can make all the difference when you are trying to conceive.

Please see the User Reference Guide for complete instructions on “how to start your next cycle”. OVWatch® can be used for this pregnancy and subsequent pregnancies, and unlike urine based products can be shared with a friend after you are pregnant.

With OV-Watch’s Advanced Technology, you will get Advanced Notice of ovulation. It is a common misconception for couples trying to conceive that they should only have intercourse when the female is ovulating. It is true that the time of ovulation is when the sperm fertilizes the egg for conception; however, the day of ovulation is not the only day that is considered “fertile”.

According to several published medical articles the highest probability of conception occurs with intercourse on the days prior to ovulation, rather than the day of ovulation itself. Most health experts believe a woman’s cervical mucus is at its most fertile stage in the days before ovulation1. And since sperm is reported to live for 6 days in the genital tract, having intercourse on those four days before ovulation may hold a woman’s highest probability of conception for that month.

OV-Watch differs from the LH urine stick tests, in that it detects the 4 crucial days before ovulation, as opposed to the LH test sticks that simply detect the LH surge that is 12-24 hours before ovulation.

Using urine strips and charting temperature to identify when you are ovulating can be messy, inconvenient, and may lead to inaccurate results. Urine testing for the LH surge may miss ovulation in up to one third of women. A woman’s LH surge is detected in the urine only 12-24 hours before ovulation.

Only OV-Watch’s patented technology can find the 4 days before you ovulate in an easy to use, lightweight, wrist -mounted fertility predictor. Those 4 days do make all the difference when trying to conceive. Why waste any more time.

Laura asks…

why do ovulation occur from alternate ovary every month?

Pregnancy Advisor’s answers:

What is Ovulation?
Ovulation refers to a specific phase in your menstrual cycle. Known as the ovulatory phase, it is during this time that your body releases an egg for fertilization. During the ovulatory phase, your body sends a series of signals that trigger an increase in the levels of estrogen in your body. In turn, this increase sets off a rise in luteinizing hormone (called the LH surge), a special hormone that helps you ovulate. When this LH surge reaches a certain point, one of your ovaries releases an egg. This egg will then travel down the fallopian tubes in order to be fertilized.

When Does Ovulation Occur?
It can be hard to predict exactly when ovulation occurs. This is because every woman’s cycle is different and can even vary individually from month to month. Typically, it is assumed that every woman has a cycle around 28 days in length. However, your cycle may last anywhere from 21 to 35 days in length. Ovulation occurs at different times in different women, depending upon the length of your menstrual cycle.

A good rule of thumb is to remember that ovulation typically takes place about two weeks before menstruation. This means that, if you have a 28-day cycle, you will ovulate around Day 14. However, few women ovulate like clockwork. As a result, ovulation can occur anywhere from Day 8 to Day 20 depending on the length of your cycle. In order to find out when you ovulate, it is necessary to look closely at specific signs that your body gives off.

Why You Need to Know
So why would you want to know when you are ovulating in the first place? Well, women find that knowing when they ovulate helps to provide them with control over their own fertility. Knowing when you ovulate can help you:

* Track your menstrual period: Keeping track of your ovulation will help you to predict when your menstruation is going to arrive, so you won’t be caught off guard. It is also especially useful for women with irregular periods or endometriosis, who often don’t ovulate.
* Get Pregnant: It is during ovulation that you are at your most fertile. If you are trying to get pregnant, timing intercourse around your ovulation can greatly increase your chances of conception.
* Preventing Pregnancy: Women who are sexually active but who don’t want to get pregnant sometimes monitor their ovulation in order to prevent pregnancy. By refraining from sexual intercourse around the time of ovulation, you can reduce your chances of getting pregnant.
