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.
It cannot and should not be used as an aid to preventing pregnancy. This calculator is provided for educational purposes only. No matter the length of her period, every woman ovulates about 14 days before her next period. The first sign to look for is mucus. The mucus, which is secreted thanks to an increase in estrogen, means your cervix is ready to be penetrated by sperm to get pregnant.
After the egg is released in your body, both estrogen and progesterone are flowing. But this method is a bit tricky for women with irregular cycles. Because the temperature change indicates the egg has already released, it means you need to have sex just before the increase in order to hit your fertile window. Find out how a more healthy lifestyle increases your chance of pregnancy and having a healthy baby.

Your chance of getting pregnant is dramatically increased if you have sex on the day of ovulation, or two days before that. When are you more likely to conceive? Ovulation Calculator What day did you your most recent period start? What is an ovulation calculator and how does it help you 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:. Facts about timing Ovulation is when a mature egg is released from the ovary. A period is when you bleed or menstruate. 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. 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 If your average menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,20 and If you have shorter cycles, say 21 days, ovulation happens around day 7 and your most fertile days are days 5, 6 and 7.
FACT A woman can only get pregnant on a few days during her menstrual cycle. 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. Getting the timing right If you're trying to get pregnant, timing is everything. If you are trying to get pregnant, it's helpful to know when you ovulate.
Ovulation is when an egg is released from an ovary. Your ovulation period lasts for 12 to 48 hours. However, since sperm are hardy and can survive in the female reproductive tract for around 72 hours, you can get pregnant anywhere from five days before you ovulate to a day after you ovulate. This period is known as your fertile window.
Timing sex during this six-day fertile window makes you significantly more likely to conceive, according to research. There are many methods of tracking and predicting ovulation so you can try to figure out when you are most fertile. An ovulation day calculator may provide an estimate, but isn't always the most accurate of methods, especially if you have irregular periods. Some ways to try to pinpoint your ovulation period at home include over-the-counter ovulation predictor kits , body basal temperature charting , and checking for fertile cervical mucus.
Each kit comes with five or so test strips or sticks, and manufacturers typically recommend you test your urine for several days leading up to your suspected ovulation day. This makes this method can potentially costly, especially if you have somewhat irregular periods and you have to test for many days or months on end. Among no-cost home ovulation-tracking methods, checking the texture of your cervical mucus may work best. According to research, people who had sex when they had slippery, egg-white-like cervical mucus associated with your ovulation period were two to three times more likely to conceive than those who had scant or absent mucus secretions typical at the very start of your menstrual cycle.
Unfortunately, there's no completely accurate method to detect that you are about to ovulate. It's possible for an ovulation predictor kit, body temperature charts, and cervical mucus patterns to all indicate a slightly different ovulation day.
Researchers found a day spread of observed ovulation days even among a group of people with "clockwork" cycles, and a similar variation for people whose cycles were a little longer or shorter. Another group of researchers set out to pinpoint the most commonly fertile day in the menstrual cycle across the general population—including those with irregular cycles—using menstrual period surveys and ultrasound measurements rather than ovulation signs. By day 25 LMP, the statistical probability of conception is zero, according to the data.
Some people do not ovulate regularly, or at all.
