But there are times in your menstrual cycle when you're at your most fertile, and this is when you're most likely to conceive. Your menstrual cycle begins on the first day of your period and continues up to the first day of your next period. You're most fertile at the time of ovulation when an egg is released from your ovaries , which usually occurs 12 to 14 days before your next period starts.
This is the time of the month when you're most likely to get pregnant. It's unlikely that you'll get pregnant just after your period, although it can happen.
It's important to remember that sperm can sometimes survive in the body for up to 7 days after you have sex. Getting the timing right If you're trying to get pregnant, timing is everything. What are the chances? Having sex as close as possible to the time of ovulation increases the chance of pregnancy. If she has sex five days before she ovulates, her probability of pregnancy is about 10 percent.

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 average , ovulation 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. Enter your information What was the date of the first day of your last menstrual period?
