Ovulation usually occurs in the middle of your menstrual cycle — about two weeks before your period — but not everyone's cycle is regular. Even for those with a regular cycle, it's possible to ovulate earlier or later. This can shift the fertile window by a few days in a given month.

The probability of conceiving if you have sex two or three days before your period is extremely low. Since your egg lives for around 12 to 24 hours after it is released, this means your fertility window closes soon after you ovulate. However, there is always a risk of pregnancy.

Yes, you can get pregnant right after your period. The likelihood of this happening, however, depends again on when you ovulate. In women with a 28-day, regular cycle, ovulation usually begins at day 14, which would be seven days after the end of a week-long period.

Most women ovulate anywhere between Day 11 – Day 21 of their cycle, counting from the first day of their last period. This is your “fertile time” and when sexual intercourse has the best chance of producing pregnancy. Ovulation can occur at any point during this window and may occur on a different day each month.

Although it is possible to get pregnant in the days leading up to your period, it isn't likely. You can only get pregnant during a narrow window of five to six days a month. When these fertile days actually occur depends on when you ovulate, or release an egg from your ovary.

The first step is to learn the days when you're most fertile. Most women have a 28-day menstrual cycle. That means you have about 6 days each month when you can get pregnant. That includes the day that one of your ovaries releases an egg, called ovulation, and the 5 days before.
