If you are trying to become pregnant, your chances will be improved if you have sex at a particular time of your cycle. Knowing when you ovulate – when an egg is released from your ovaries – is the key to knowing when that right time is.

When you are most fertile

The 5 days before ovulation, together with the day you ovulate, are the days when you are most likely to conceive. Sperm can live up to 5 days inside your body, so if you have sex up to 5 days before your egg is released, you can get pregnant. After ovulation, though, your egg can only live for 12 to 24 hours. After this time is up, your time for getting pregnant has gone for now till the following month.

Your chances of getting pregnant are at their highest in the 3 days leading up to and including ovulation.

Predicting ovulation

Ovulation usually happens about halfway through your menstrual cycle, about 14 days before the first day of your next period, but the exact time can vary. Although signs that you are about to ovulate can be subtle, there are some things you can pay attention to and track over time to help you predict your fertile window.

Changes in mucus

Noticing how your vaginal secretions change during your menstrual cycle is the basis of the Billings ovulation method. Around the time of ovulation, you may notice your secretion is clear, stretchy and slippery — similar to egg whites. After ovulation, when the chances of becoming pregnant drop, the secretion tends to become cloudy and thick, or disappear entirely.

Changes in body temperature

When you’ve just ovulated, your body temperature may increase very slightly, by about half a degree Celsius. If you’re using temperature as a means of keeping track of when you are most fertile, you need to use a special thermometer to take your temperature every morning before you get out of bed. If you record the readings every day using a graph or a spreadsheet, it’s possible to learn your pattern over time. The time when you are most fertile is 2 to 3 days before the rise in temperature.

Other signs

There may be other signs that you are near the time of ovulation, such as mild abdominal cramps, breast tenderness or increased sex drive. However, using these signs to predict when you’re fertile is not the most reliable method.

Using ovulation calculators and kits

Ovulation calendars and kits can also help you predict ovulation.

Ovulation calendars are available on websites such as www.yourfertility.org.au, and use the date of your last period and the length of your cycle to predict when you are likely to be most fertile.

Home ovulation predictor kits are available from pharmacies. You use the kit a few days before your predicted ovulation day, to test for a rise in the level of a hormone called luteinising hormone (LH) in your urine. A positive result indicates you will ovulate within the next 24 to 36 hours.

A blood test, which your doctor can order, can also detect ovulation by measuring levels of the hormone progesterone.

If you are trying to get pregnant, there are also a number of other things you should consider, such as taking folate, maintaining a healthy diet and making sure your vaccinations are up to date.

How many days after ovulation can you get pregnant?

It is possible to become pregnant after ovulation. When a person has sex within 12–24 hours after the release of a mature egg, there is a high chance of conceiving.

Ovulation occurs when one of the ovaries releases a mature egg. This is the time when the body is ready to receive sperm for fertilization.

If fertilization does not occur, the egg disintegrates into the uterine lining. The body will then shed the remains during a person’s monthly period.

Ovulation lasts anywhere from 12–24 hours. After the ovary releases an egg, it survives for about 24 hours before it dies, unless a sperm fertilizes it.

If a person has sex days before or during the ovulation period, there is a high chance of conceiving. This is because sperm can survive up to 5 days in the cervix. Therefore, it is important to understand the fertile window.

The fertile window is the period of time during which it is possible to become pregnant from sex. This is the day of ovulation plus the amount of time that sperm can live inside the cervix before it fertilizes the egg.

According to the American College of Obstetricians and Gynecologists (ACOG), a person can become pregnant if they have sex anywhere from 5 days before until 1 day after ovulation.

Depending on the menstrual cycle, the fertile window may vary from one person to another.

To calculate the fertility window, a person should note the first day of a period until the next period occurs. This timeframe is the menstrual cycle. On average, most people who menstruate have a 28-day cycle.

However, according to the Office on Women’s Health, for some, it may last 21–35 days.

According to the ACOG, ovulation occurs around day 14 of the menstrual cycle.

A person with a 28-day cycle, for example, will have their fertile window 5 days before the ovulation date.

Pregnancy is possible 12–24 hours after ovulation. This is because the released egg can only survive 24 hours before the sperm can no longer fertilize it.

The likelihood of getting pregnant on the days before and after ovulation varies from one person to another.

An older study from 1995 looked at the timing of sexual intercourse in relation to ovulation and the likelihood of conception.

Out of 221 healthy women, there were 192 pregnancies. Researchers concluded they could estimate the odds of becoming pregnant on each day of the fertile window as between 10–33%, depending on the day.

5 days before ovulation	10%
4 days before ovulation	16%
3 days before ovulation	14%
2 days before ovulation	27%
1 day before ovulation	31%
Ovulation day	33%

The same study authors also note there could be a 12% chance of conceiving on either day 7 before ovulation and the day after ovulation.

However, the chances of becoming pregnant before or after ovulation depend on several factors, including:

age
frequency of sexual intercourse
menstrual cycle

For those trying to conceive, tracking ovulation is crucial to ensure they identify the most fertile days in the menstrual cycle.

Here are some of the methods a person can use to track or predict ovulation.

Basal body temperature charting

Basal body temperature (BBT) is the temperature when the body is at rest.

Charting BBT for a series of months by measuring every morning after waking up will help predict ovulation.

During or when ovulation approaches, there is a slight increase in BBT. A person can use a digital thermometer to track these small changes in temperature.

Monitoring BBT can help tell when ovulation occurs and therefore predict the days in the cycle when pregnancy is possible.

Ovulation predictor kits

Using ovulation predictor kits, such as test strips and digital tests, will help measure the level of luteinizing hormone (LH), which usually rises during ovulation.

A person needs to take tests for consecutive days to detect the rise in LH.

Once they notice a consistent rise, experts recommend having sex daily for the next couple of days to increase the chances of pregnancy.

Cycle charting apps

Several cycle apps, such as the Clue period tracker and Flo period ovulation tracker, can help calculate the ovulation period and fertile window.

Charting ovulation using these apps will indicate the ovulation date and days when a person’s body is most fertile.

Fertility monitors

For people trying to conceive or wishing to avoid pregnancy, using fertility monitors to track ovulation can help people plan intercourse.

Fertility monitors work by measuring significant body changes, such as BBT, heart rate, and breathing.

By compiling this data, the fertility monitor can predict the fertile window.

Cervical mucus method

Observing cervical mucus can give an idea of when a person may be ovulating.

When ovulation approaches, the cervical mucus changes to a thin, clear, stringy, slippery consistency. It may look similar to raw egg whites.

The mucus allows the sperm to swim to the released egg during intercourse.

Ideally, this is the ideal time to have sex due to the high chances of becoming pregnant.

Watching ovulation signs, such as a slight increase in BBT, changes in cervical mucus, and increased sex drive, can help determine the best time to have sex to boost chances of becoming pregnant.

In addition, having sex during the fertile window increases the chances of conception. During this timeframe, the body is ready to receive sperm for fertilization.

On average, a menstrual cycle lasts between 21–35 days.

An irregular cycle or absent cycle that lasts fewer than 21 days or more than 35 days, can mean that a person is not ovulating.

A person should speak with a doctor if they do not become pregnant after 1 year of trying to conceive.

Age may also determine when to seek help. People between 35–40 years of age should speak with a doctor after 6 months of trying to get pregnant. For those above 40 years of age, a healthcare professional may run some fertility tests.

A doctor may also test for possible signs of infertility or if a person has ever had repeated miscarriages, pelvic inflammatory disease, endometriosis, prior cancer treatment, or a history of irregular periods.

A person can get pregnant 12–24 hours after ovulation, as a released egg can survive up to 24 hours within the cervix.

For those trying to conceive, it is crucial to understand the menstrual cycle.

Beyond this, a person can use methods, such as BBT charting, cycle charting apps, fertility monitors, changes in cervical mucus, and ovulation predictor kits to boost the chances of pregnancy.

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.

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.

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 fall 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.

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.

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.

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. Moreover, not the fastest fertilizes the egg: thousands of spermatozoa simultaneously break its shell.

From this follows the conclusion: modern science does not know how to determine the sex of the child during natural conception, and therefore there is no universal recipe.

How does ovulation and fertilization occur?

In the first phase of the menstrual cycle, follicle maturation begins in one of the ovaries. This small vesicle consists of an ovum enclosed in a "shell" of connective tissue. The follicle grows from 1 mm to 12–16 mm ¹ and then bursts, releasing the egg into the fallopian tube. This moment is called ovulation.

What happens after ovulation? The egg becomes available for fertilization. For this to happen, there must be enough sperm in the fallopian tube. Contrary to popular belief, the winner will not be the most agile of them all. The ovum is surrounded by a special membrane called the "radiant crown" ² (sounds very nice, doesn't it?). First, many fighters will die trying to destroy the protective shell, and only then one lucky one will get inside and fertilize the egg.

When does pregnancy occur? Right after ovulation?

The period in which a woman can become pregnant does not last very long: the egg cell lives only about 24 hours ³ . This gives us the answer to the question of how long after ovulation conception occurs - at any point in this short period. In particular, fertilization can happen almost immediately if the spermatozoa made their way into the fallopian tube even before the egg is released from the follicle.

Some women report that they did not become pregnant on the day of ovulation, but earlier or later. This is impossible in principle, and they are wrong - it's just that the actual date of this event may not coincide with the calculated one. It is normal if ovulation happened a day or two earlier or later than the plan, and under certain conditions (hormonal changes, stress, and others), it can go beyond this. More details in this article.

So how do you calculate ovulation?

Pregnancy begins after ovulation and fertilization of the egg by sperm. It's up to the small thing - to understand when this important event will happen. Take a calendar and look at our drawing. With it, you can calculate the approximate date of ovulation. But remember, this is just a prediction, and that's why we've drawn high, medium, and low pregnancy probability areas around the central day.

Do not try to get pregnant exactly at ovulation. It is better to cover the entire period of high probability with a “queue”. Start having sex for pregnancy 4 days before the planned date and do it every other day: 4th day before, 2nd day before, day of ovulation, 2nd day after, 4th day after. This will greatly increase your chances of success.

Approximate menstrual cycle schedule. Calculations are given for cycles with a duration of 25 to 31 days.

The ideal menstrual cycle is 28 days. In many articles on conception and ovulation, all the reasoning is built around this textbook case. Indeed, it is very convenient - ovulation in it occurs on the 14th day, dividing the cycle into two equal halves. Life is different from the ideal: the duration of the cycle for different women varies, but usually ranges from 25 to 31 days ⁴ .

Most likely, you will find your case in this figure, but if your cycle is shorter or longer, there is nothing strange in this - the duration is from 21 to 35 days ⁵. The following knowledge will help calculate the day of ovulation: with a change in the length of the cycle, its first part usually decreases or grows, while the second remains unchanged and is always about two weeks. Set aside 14 days back from the planned first day of menstruation - get the approximate day of ovulation.

There are many more signs of ovulation that you can check out in this article.

In terms of conception, the menstrual cycle can be divided into the following phases (shown in the figure):

Menstruation. Sex during this period can only lead to conception under very unusual circumstances. For now, relax - auspicious days ahead.
From the end of menstruation to the 6th day before the planned ovulation. The probability of conception at this time is minimal. Most likely, the egg has not only not left the ovary, but has not even matured yet.
5 to 3 days before the estimated ovulation date. The chance of getting pregnant increases, and there are two reasons for this. Firstly, the real day of ovulation does not always coincide with the calculated one. Secondly, spermatozoa know how to wait. Most of them will die in the vagina within a couple of hours - its acidic environment fights well not only with bacteria. However, those that can penetrate the uterus are able to live up to three, sometimes up to five days ⁶ .
Planned day of ovulation plus or minus two days. During this period, a woman is most fertile. Given the lifespan of the egg and sperm, sex these days is highly likely to lead to pregnancy. Of course, if there are no factors that can interfere with this.
3 to 4 days after estimated ovulation date. The chance of getting pregnant is decreasing, but still remains. Do you remember that calculating the day of ovulation is not a very exact science? So anything is possible.
From the 5th day after the planned ovulation until the end of the cycle. Do not seriously expect that you will be able to conceive these days, have sex just for fun. If you have tried to get pregnant on your fertile days, you may have already conceived!

What should be the feeling after ovulation?

During the menstrual cycle, there is only one period in which a woman feels the changes taking place in her body. This is menstruation itself, and the sensations from it are very familiar to you. All other phases of the cycle are "asymptomatic".

The answer to the question of how to understand that ovulation was successful is prosaic: no way. The woman's body simply does not have a mechanism that would tell the brain about it. So, if you woke up with the certainty that today is that very day, these are just mind games that frolicked in a dream with the thought you desired about the joy of motherhood. Although, coincidences also happen :)

Even if the pregnancy has not even begun, but now you need to prepare for childbirth - study useful articles and look for courses for expectant mothers. Take the test and find out how well you are ready for childbirth and motherhood.

When will signs of pregnancy appear after ovulation and conception?

Reliable - not soon. A regular pregnancy test will show two cherished strips only after a delay, a test with increased sensitivity or laboratory analysis - 3-4 days earlier. The final confirmation with the help of ultrasound will have to wait another couple of weeks.

Do not expect pregnancy symptoms immediately after ovulation. While the fertilized egg slowly gets from the fallopian tube to its destination, almost no changes occur in the body. The first signs of pregnancy will appear only 6-10 days after ovulation, when the embryo attaches to the wall of the uterus ⁷ . And they will be almost invisible:

Change in basal body temperature. If you have been measuring your basal temperature all this time, you will notice a slight drop on the chart, and then a rise to a new, higher level.
Implantation bleeding. In the process of attaching the embryo to the wall of the uterus, the endometrium is damaged - its inner mucosa. In this case, the expectant mother may notice slight spotting.
Pain or cramps in the lower abdomen. Along with bleeding, mild pain may come. Therefore, women often attribute these first signs of pregnancy to early menstruation.

Why did not conception occur after ovulation?

You tried to get pregnant, but your next period started right on time. Why did it happen? Only your doctor can accurately answer this question, but we will list some likely causes.

Anovulatory cycle. Some menstrual cycles do not ovulate and this is perfectly normal ⁸ . They are called anovulatory and are needed by the body so that it can take a little break from the constant preparation for pregnancy. During the year, a woman experiences 1–2 anovulatory cycles.
Gynecological diseases. Sometimes conception after ovulation does not occur because the woman has gynecological diseases. Inflammation of the ovaries, blockage of the fallopian tubes, and some other conditions can significantly reduce the likelihood of pregnancy, and under certain conditions, even make conception impossible. A gynecologist can identify such diseases and prescribe treatment.
Immune or autoimmune reactions. Spermatozoa are very unusual cells. They contain only half of the chromosome set, and from the point of view of the immune system, they look like mutants. Everything is so bad that nature even had to collect them in special refrigerated bags and hang them outside the man's body. In some cases, the immune mechanisms of a woman can deal with spermatozoa at the time of passage of the cervix ⁹ . Autoimmune reactions also occur when a man's body destroys them. If the doctor considers that this may be the reason for unsuccessful attempts at conception, he will prescribe tests for both the expectant mother and the future dad.
Poor semen quality. After intercourse, spermatozoa will have to overcome the champion's obstacle course - survive in the aggressive environment of the vagina, break through the cervical mucus in the cervix, get to the right fallopian tube, destroy the protection of the egg. If the spermatozoa of the future dad are not very active, they can go the distance before conception. To exclude this cause, it is necessary to make a spermogram.

When conception occurs after ovulation, future parents take it for granted. If pregnancy does not occur, they often begin to panic and think with horror that they will never hear ringing children's laughter and light steps of tiny legs in their house. Drive unconstructive thoughts away - many couples were able to conceive far from the first time. Try again next month. We believe you will definitely succeed!
