Nov 13, · Knowing the days you are most likely to be fertile can increase your chance of getting pregnant. The typical menstrual cycle is 28 days long, but each woman is different. There are about 6 days during each menstrual cycle when you can get pregnant. This is called your fertile window. By learning when you ovulate, you can predict when you’re likely to be fertile. This calculator gives approximate ovulation dates and fertile times for women who have regular periods. (Regular periods mean having a period every 21 to 35 days.) Fertility charting, basal temperature tracking, and purchased ovulation test kits can also be used.
A woman is able to become pregnant what day do you ovulate only during a certain part of her monthly cycle. That is just before and during ovulation. This calculator gives approximate ovulation dates and fertile times for women who have regular periods.
Regular periods mean having a period every 21 to 35 days. These are especially useful if a woman has irregular periods. Please note that the date you enter in the calculator may result in an ovulation date that has already passed.
This will occur if you are nearing your next menstrual start date. This calculator is not meant for women who are already pregnant.

Studies have shown that to increase your chances of getting pregnant, you should have sex once a day or every 2 days during your fertile days. Sperm can live for a few days and the egg can live about a day. Most experts suggest you try every other day or every day starting about 5 or 6 days before you expect to ovulate. Continue up through the day of ovulation or the next day.
On average, a woman with a regular day cycle ovulates on about the 14th day of each cycle. For example, during a day cycle 4 days shorter than the averageovulation takes place on about the 10th day. Similarly, changes are made in the opposite direction for cycles longer than 28 days. Stress, illness, and other things can also affect the timing of ovulation. Irregular cycles or cycles that are shorter than 21 days or longer than 35 make calendar prediction of ovulation unreliable.

When do you ovulate?
How long do you ovulate? For women who have a 28 to day menstrual cycles, ovulation can take place between days 11 through 21, but it will only occur on ONE of these days. Remember, this is just an average of days that ovulation could take place—every woman’s cycle is different. Know when you ovulate: Ovulation usually happens 14 days before your next period begins, but it can vary from month to month -- even in women with regular cycles. Jan 29, · Generally, you ovulate in the middle of your menstrual cycle. If you have an average day cycle, you may ovulate around day However, lengths of normal cycles can vary from 21 to 35 days. Some women ovulate around the same day each cycle, but for others the timing is hard to pinpoint.
During each monthly cycle, healthy couples who aren't using birth control typically have around a 25 to 30 percent chance of getting pregnant, though it can vary widely depending on the circumstances, particularly related to your age. That's actually a surprisingly high percentage considering that you can only conceive around the time of ovulation — a small window each month when the egg is viable between 12 and 24 hours and open for the business of fertilization.
Doesn't sound like much of an opening? Consider, then, that sperm are able to live to fertilize an egg 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 before it makes its trip down the fallopian tube.
And remember: It only takes one sperm to make a baby. Of course, having sex the day you ovulate would be ideal, since after that the window tends to close until the next cycle. So recognizing the signs of ovulation is key when pregnancy is the goal.
Ovulation is the release of a mature egg from one of the ovaries, which happens every month. A woman is most fertile around the time of ovulation. Ovulation usually occurs halfway through your menstrual cycle, or around day 14 of the average day cycle counting from the first day of one period to the first day of the next.
But as with everything pregnancy-related, there's a wide range of normal here since cycles can last anywhere from 23 to 35 days, and even your own cycle and time of ovulation may vary slightly from month to month. An egg can be fertilitzed for between 12 and 24 hours after ovulation.
The specific length of time that it takes for the egg to be released by the ovary and picked up by the fallopian tube is variable but occurs 12 to 24 hours after a surge of the hormone LH as described below.
There are a number of ways to predict when you might start ovulating. Here's how to prepare for ovulation and pinpoint the timing:. Keep a menstrual cycle calendar for a few months so you can get an idea of what's normal for you — or use tools that can help you calculate ovulation. If your periods are irregular , you'll need to be even more alert for other ovulation symptoms.
Can you feel ovulation happening? 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.
Your basal body temperature , or BBT, that is. Taken with a special, basal body thermometer, basal body temperature 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 before ovulation, estrogen dominates.
During the second half after ovulation, there's a surge in progesterone, which increases your body temperature as it gets your uterus ready for a fertilized, implantable egg. That means your temperature will be lower in the first half of the month than it is in the second half.
Here's the bottom line: Your basal body temperature will reach its lowest point at ovulation and then rise immediately about a half a degree as soon as ovulation occurs. Keep in mind that charting your BBT for just one month will not enable you to predict the day you ovulate but rather give you evidence of ovulation after it's happened. Tracking it over a few months, however, will help you see a pattern in your cycles, enabling you to predict when your fertile days are — and when to hop into bed accordingly.
Many women do find this approach a bit frustrating and it is important to know that studies have shown that the timing of ovulation does vary among women after the dip in temperature. Ovulation predictor kits are more precise. Ovulation isn't an entirely hidden process, and there are some definite physical signs of ovulation. As your body senses the hormone shifts that indicate an egg is about to be released from the ovary, it begins prepping for the incoming hordes of sperm to give the egg its best chance of being fertilized.
One detectable sign of 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, firm 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 record of your observations. The other cervical ovulation symptom you can watch for is a change in mucus.
Cervical mucus, which you'll notice as discharge, carries the sperm to the egg 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 that of 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 egg white cervical mucus is yet another sign of impending ovulation. After you ovulate, 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 you're most likely to ovulate — in plenty of time for you to do something about it.
Some women do not produce much cervical mucus, particularly those who have had surgery on the cervix for abnormal PAP smears such as a LEEP procedure. Don't want to mess around with mucus? You don't have to. Many women use ovulation predictor kits , which identify the date of ovulation 12 to 24 hours in advance by looking at levels of luteinizing hormone, or LH, the last of the hormones to hit its peak before ovulation.
All you have to do is pee on a stick and wait for the indicator to tell you whether you're about to ovulate. These approaches are more accurate than the use of apps which predict when you should be ovulating, but not necessarily when you are ovulating.
A less precise and rarely used approach is a saliva test, which measures estrogen levels 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 window pane. Not all women get a good "fern," but this test, which is reusable, can be cheaper than the kits. 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 tohour notice that standard ovulation predictors provide.
The saliva and chloride ion surge tests have not been well studied and tend to be used much less frequently. Just remember: Patience and persistence are key when you're trying to get pregnant, and there are no guarantees that you'll definitely conceive even if you are ovulating. But it can't hurt to keep an eye out for these common ovulation symptoms, then plan a candlelit dinner, draw a warm bubble bath or go on a romantic weekend getaway — whatever it takes to put you and your partner in the baby-making mood.
