Right Time For Sex , When Do You Ovulate ?

When are you more likely to conceive?

We’re talking about the 'fertile window’ – the days in a woman’s menstrual cycle when pregnancy is possible. The ‘fertile window’ depends on the length of the menstrual cycle, which varies among women.

The ‘fertile window’ is the day an egg is released from the ovary (ovulation) and the five days beforehand. Having sex (intercourse) during this time gives you the best chance of getting pregnant.

What is an ovulation calculator and how does it help you get pregnant?

This ovulation calculator or ovulation calendar can help you work out your most fertile time. These are the days you are most likely to get pregnant.

It can also estimate your due date if you do become pregnant during your next fertile days.

Others ways to help you work out when you're ovulating:

Notice changes in vaginal mucus
A few days before ovulation, you may notice your vaginal mucus becomes clear, slick and slippery, and feels a bit like egg white.
This is a sign that ovulation is about to happen. It’s the best time to have sex, as sperm travel more easily in this kind of mucus.
Use an ovulation predictor kit
You can use a predictor kit from a supermarket or pharmacy, to test your urine for signs of ovulation. If you start testing your urine a few days before the day you next expect to ovulate, a positive result means you are going to ovulate within the next 24 to 36 hours (one to two days).

Facts about timing

Ovulation is when a mature egg is released from the ovary. The egg then moves down the fallopian tube where it can be fertilised. If sperm are in the fallopian tube when the egg is released, there is a good chance that the egg will be fertilised, creating an embryo, which can grow into a baby.

Pregnancy is technically only possible if you have sex during the five days before ovulation or on the day of ovulation. But the most fertile days are the three days leading up to and including ovulation. Having sex during this time gives you the best chance of getting pregnant.

By 12-24 hours after ovulation, a woman is no longer able to get pregnant during that menstrual cycle because the egg is no longer in the fallopian tube.

There’s almost no chance of getting pregnant if you have sex before or after the fertile window (but if you’re not trying to get pregnant, don’t rely on this – contraception is your best option!).

How to know when you’re ovulating

Knowing when you ovulate can help you plan for sex at the right time and improve your chance of getting pregnant. You can keep track of your menstrual cycles on a chart, in a diary, or on a free period-tracker app on your smartphone.

To work out the length of your menstrual cycle, record the first day you start bleeding (first day of your period). This is day 1. The last day of your cycle is the day before your next period begins.

What is a ‘menstrual cycle’ and a ‘period’?
Some people think the ‘menstrual cycle’ and a ‘period’ are the same thing.
A period is when you bleed (or menstruate).
A menstrual cycle starts on the day when a period starts (day 1) and ends the day before the next period. A cycle’s length is considered normal if it’s between 21 and 35 days. They can vary between women and from one cycle to the next.
Working out your ‘average’ menstrual cycle length
If your menstrual cycles are different lengths (most women’s cycles are) you can work out your average cycle length.
The number of days in a woman’s menstrual cycle can vary month to month. Periods are not always regular. It can be useful to work out an ‘average’ cycle length, based on the length of three menstrual cycles, to estimate when you’re most likely to be ovulating.
If you add the number of days in three cycles and divide the total number by three, it gives you your average cycle length.

Example
Sarah tracked her last three menstrual cycles by counting the time from the first day of one period, to the day before the next period.
Cycle 1 was 28 days; Cycle 2 was 32 days; Cycle 3 was 27 days
28 + 32 + 27 = 87
87 divided by 3 = 29
So the average length of Sarah’s menstrual cycles is 29 days.
Working out your most fertile days
When you know your average menstrual cycle length, you can work out when you ovulate.
Ovulation happens about 14 days before your period starts.
- If your average menstrual cycle is 28 days, you ovulate around day 14, and your most fertile days are days 12, 13 and 14.
- If your average menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,20 and 21.
- If you have shorter cycles, say 21 days, ovulation happens around day 7 and your most fertile days are days 5, 6 and 7.
Your most fertile days are the three days leading up to and including the day of ovulation.
Some women have very irregular cycles or find it difficult to work out an average cycle length. This can make it hard to work out when ovulation happens. If it’s all too hard, having sex every 2-3 days covers all bases and improves your chance of getting pregnant.

Myth busting

MYTH: A woman can get pregnant any time of the month.
FACT: A woman can only get pregnant on a few days during her menstrual cycle.

Why?

Because eggs and sperm only live for a short time:

Sperm live for around five days.
Eggs can only be fertilised for around 24 hours (one day) after being released from the ovary.

Eggs and sperm need to come together at the right time for fertilisation to happen to create an embryo.

Getting the timing right

If you're trying to get pregnant, timing is everything. Dr Karin Hammarberg explains how to work out when you are ovulating and the right time to have sex to improve your chance of pregnancy.

What are the chances?

Having sex as close as possible to the time of ovulation increases the chance of pregnancy.

If a woman has sex six or more days before she ovulates, the chance she will get pregnant is virtually zero.

If she has sex five days before she ovulates, her probability of pregnancy is about 10 percent.

If she has sex on the day of ovulation, or the two days before, the chance of getting pregnant is around 30 percent.

These are average figures and depend on a woman’s age.

When does preconception health begin?

Professor Sarah Robertson, Director of Robinson Research Institute, University of Adelaide, highlights the key time before pregnancy that your health is most important to ensure your child has the best start to life.

How to know you are ovulating

Kerry Hampton, a registered nurse and fertility specialist, discusses the importance of fertility awareness, and how to determine your fertile window to improve your chances of conceiving.

Your Best Days for Making a Baby

Written by Kara Mayer Robinson

Brandi Jeter Riley and her husband, Terrence, were ready to give their 8-year-old daughter a baby sister or brother.

When Riley didn't get pregnant right away, she worried about infertility. But before seeing a specialist, she tried something she hadn't done before -- tracking her cycle and timing it right.

It was a success. Less than 2 months later, Riley, who lives in Oakland, CA, was pregnant. "Nine months later, I was giving birth to my little baby boy," she says.

"When a couple is having issues getting pregnant, the first step is to make sure they're doing it right," says Kara Manglani, a certified nurse midwife and fertility expert in New York. They need to learn about the woman's menstrual cycle and ovulation -- that time every month when one of their ovaries releases an egg.

When Is the Best Time to Get Pregnant?

"Most pregnancies result from sex that happened less than 2 days before ovulation," Manglani says. But you can get pregnant earlier or later. "Sperm can live in fertile cervical mucus for up to 5 days," she says. An egg can live up to 24 hours after ovulation.

Generally, your best chance of getting pregnant is 12-16 days before your period, says Edward Marut, MD, a reproductive endocrinologist with Fertility Centers of Illinois.

"The tricky part is identifying when ovulation occurs," Manglani says. Every woman's menstrual cycle is different. Many women think they ovulate on the 14th day of their cycle. But that's a myth. Most don't.

Try one or more of these methods to figure out when you ovulate.

Track Your Basal Body Temperature

This is your temperature when you first wake up in the morning. When you ovulate, it goes up slightly and stays up until your next period.

To track it, you'll need a basal body thermometer, which measures small changes. You can get one at most drugstores and supermarkets.

Take your temperature before you get out of bed every morning. Note the first day it goes up.

"Once you identify the day you ovulated, you can predict that ovulation will happen on or close to that day in future cycles," Manglani says.

Try an Ovulation Predictor Kit (OPK)

OPKs are at-home test kits that detect a surge in luteinizing hormone (LH), which your body releases 24-48 hours before you ovulate.

In the middle of your cycle, you'll test your urine every day for 5-10 days. When your LH goes up, it's time to start trying to conceive.

There are two types of OPKs:

Ovulation test strips. These are paper strips you dip into a cup of your urine. A few minutes later, a line shows up. Depending on how dark it is, you'll know if you're about to ovulate.

Digital ovulation tests. They're typically more expensive than test strips. With a digital test, you hold a stick under your morning stream of pee. The digital monitor tells you if you're likely to start ovulating.

You can get OPKs at many drugstores and supermarkets. Most have clear instructions and a toll-free number for questions.

OPKs are helpful if you have sex less often or you'd like to time it more precisely, Marut says, but they're not always accurate.

Use a Cycle Charting App

Phone apps can help you chart your cycle. You record details like the first day of your period, OPK results, and basal temperature. You'll get alerts when you're likely to be more fertile.

The drawback is most use a standard 28-day cycle, with ovulation on day 14, which isn't accurate for many women.

Fertility Monitors

Fertility monitors use urine test strips and a digital monitor to measure your LH and estrogen levels. They find your peak days and the few days leading up to them, and store your info over multiple cycles.

They're high-tech, but pricey -- about $200 and up. And like tracking apps, they often use a standard 28-day cycle.

Cervical Mucus Method

Hormones that control your menstrual cycle also affect your cervical mucus. The few days after your period are "dry days," with no mucus. As an egg matures, mucus develops in your vagina and enters your vaginal opening. It may be white, yellow, cloudy, or sticky.

Right before ovulation, you have "wet days," where mucus is clear and slippery and looks like egg whites. That's when you're most likely to conceive.

When to Have Sex

"Timing sex as close to ovulation as possible is important," Manglani says. Your best bet is to have sex often. Try doing it every day starting 5 days before ovulation. Keep going one day after ovulation.

Marut has a different take. Get in a routine of having sex every other day, he suggests, and don't worry about it.

Another option: Try the "sperm meets egg plan." Have sex every other day starting on day eight of your cycle. Start an OPK on day 10. "Once you have a positive result on your OPK, have sex every day for three days," Manglani says.

If you don't get pregnant in 6 months, see a doctor. "Most regular OB/GYN offices can start a fertility workup," Manglani says. Or reach out to a board-certified reproductive endocrinologist.

When is a woman most fertile?

If you are a woman taking precautions to prevent pregnancy, or if you are thinking about pregnancy in some way in the future, the issue of fertility usually remains in the background.

The question of when a woman is most fertile has two aspects.

First, is the menstrual monthly cycle and the period when a woman is most fertile.

To figure out the arithmetic, a fertility calendar or an ovulation calculator will help. The second aspect of the question concerns biological age and the stage of life at which women are most fertile. In our article, we will look at the monthly cycle, the days that are the most fertile during this cycle, and various means of monitoring and predicting ovulation. This makes it possible to predict the time of maximum fertility with some accuracy.

Second , we look at the stages of fertility at various times in a woman's life and their impact on her ability to conceive.

It is well known that fertility peaks at age 20 and begins to decline after age 30; after 35 years, natural conception rates begin to drop sharply. However, in today's society, many women, for understandable financial and social reasons, choose to delay childbearing until the age of thirty. Thus, we are faced with the paradoxical situation where many women, who have long sought to prevent pregnancy in their younger years, find themselves in a situation where they begin to look for ways to increase their chances of conceiving. nine0003

When is a woman most fertile? What does the menstrual cycle show?

In a woman, the ability to conceive is maximum a day or two before and after ovulation. This is when the egg is released from the ovaries. You can calculate with a reasonable degree of accuracy when ovulation will occur, especially if your cycle is regular, anywhere between 24 and 35 days. Consider the start of your period (bright spotting) as the first day of your cycle, and the day before the next as the end of your cycle. Ovulation usually occurs 12-16 days before the start of the next cycle. Thus, if you have a regular 28-day cycle, then the indicator remains the same: ovulation occurs on the 12th-16th day. However, fertile time is not limited to these few days. Remember that you can get pregnant if you have unprotected sex at any time during the week before ovulation, as sperm can live in a woman's genital tract for up to seven days. nine0003

Fertility specialists generally advise that if you are hoping to get pregnant, it is advisable to specifically schedule contacts around this time, as it can be difficult to calculate the exact day of ovulation, and trying to have sex on a schedule can cause unnecessary stress and anxiety. For the best chance of getting pregnant as long as there are no underlying fertility problems, it is recommended to have intercourse every 2-3 days during your cycle. In addition, fertility calendars, an ovulation test, and self-monitoring for signs of ovulation can help predict the ideal time to conceive. nine0003

Menstrual calendar

It could be an old-fashioned pen and paper, a spreadsheet, or one of the many online calendars available. They are also known as ovulation calendars or ovulation calculators. They all do the same thing: keep track of your menstrual cycle dates and use the 12-16 day calculation outlined above to determine the days on which you are most likely to conceive.

Ovulation Tests

These are test kits that measure the level of luteinizing hormone (LH) in your urine. The essence of the measurement is to capture the surge in LH levels that occurs during your cycle a couple of days before ovulation. There are also tests that measure the same hormone pulsation but use a saliva sample. In these tests, saliva takes on the appearance of a fern-like pattern when it dries on glass. However, the most accurate analysis that allows you to track the LH peak is a urinalysis (rarely used in routine practice). nine0003

Self-monitoring for signs of impending ovulation

Self-monitoring includes taking temperature every morning after waking up, as well as monitoring the quality and consistency of vaginal mucus secretions. This must continue for several months so that ovulation can be tracked. This is the least reliable of the methods, because there can be many different causes of body temperature fluctuations (night rises, colds, blood sugar fluctuations), and in fact, many girls rightly find this procedure tedious and difficult to perform. nine0003

Fomin's clinic — a network of multidisciplinary clinics

Today's world is full of information: literally with one click, each of us can open the Universe and learn everything - from string theory to concert posters for the next week. It is all the more interesting that, having unlimited access to knowledge, we still live in myths - and sometimes they arise, including thanks to the Internet, replicating untruth and absurdity.

We have prepared for you a short “blitz” of six questions or myths about pregnancy and conception, so that you are fully equipped and do not believe the tales on the Internet. nine0003

Well... not exactly. Firstly, the idea of a “full examination” is a clear exaggeration, because there is no single list of tests that an expectant mother needs to pass. Ideally, visit a doctor three months before the end of contraception, get tested for STIs and antibodies to rubella. If additional examinations are required, you will be individually prescribed everything you need - including, probably, vaccinations that should be “updated”. As for alcohol and smoking, they are really contraindicated at the stage of pregnancy planning, so if you have these addictions, you will have to give them up. However, it should be remembered that smoking cessation applies to both electronic cigarettes and “passive smoking”, which can lead to dangerous consequences for the fetus. nine0003

Spoiler: no big deal. Do not panic and blame yourself for all mortal sins because of a glass of wine. With the recognized insecurity of alcohol, scientists have proven that a woman drinking 1-2 servings a couple of times a week should not harm the unborn child. For men, the allowable figures are slightly higher - 3-4 doses of alcohol per week. The main thing is to know the measure and not to overdo it.

There is, of course, a simplified formula for calculating the estimated due date: plus 7 days and minus 3 months from the date of the last period, but to be honest, it doesn’t work like that: the fact is that it is very difficult to “program” pregnancy and make sure that the child is born when you want. If you have a plan and are going to stick to it, be prepared for the fact that things can go wrong, if only because:

the duration of pregnancy is not 40 weeks, but 37-42 weeks, which means that you can easily get into a five-week “loop”, which will reduce the chances of fulfilling the plan to zero;

with regular sex, the probability of conception is not 1 time per month (exactly when you guessed it), but 1 time per year.

Nothing is impossible... However, it is worth clarifying the question a little: you can get pregnant only during ovulation (more precisely, shortly after it), but you can have sex, which will lead to a long-awaited pregnancy, on different days. Of course, on the days of menstruation, the probability is lower than on the days that precede ovulation, but on none of the days of the menstrual cycle this probability is not zero. nine0003

Let's just say that trying multiple times a day is a bad idea. Why? At least because ejaculation more than once a day worsens the quality of sperm, as a maximum - such perseverance and zeal can create tension in the relationship of partners. Doctors advise to have sex every 2-3 days throughout the cycle, and not try to guess the moment and throw all your strength into this short period.

Planning the sex of a child is an extremely prolific topic for myth-makers. Some believe that with the help of a special table that takes into account such indicators as the age of the father and mother, the month of conception, it is possible to accurately calculate the sex of the child. This "method" is anti-scientific and has nothing to do with reality. nine0003

Another myth is that you have to get pregnant on the day you ovulate to have a boy. Previously, scientists really believed that X and Y spermatozoa differ from each other (Y are faster), and the sex of the child is formed due to the first one that broke through the defenses of the female egg. If you want to conceive a boy, you need to have sex on the day of ovulation so that the Y-sperms responsible for the "male sex" have more time to get to the egg located farthest from the entrance to the uterus. nine0003

However, this myth does not stand up to criticism: the fact is that there is no difference between the X and Y chromosomes, which means that the sex of the child does not depend on which of the sperm reaches the egg first.
