When to have sex to get pregnant?

Once an egg is released, it has 24 hours to get fertilized before it dissolves. However, sperm can live for up to 5 days inside a woman. From 5 days before ovulation through the day of ovulation is the Fertile Window.

According to Dr. Wilcox, the likely hood of conceiving is distributed for a total of 6 days including the ovulation day. You can increase your chances of getting pregnant if you have more than one relationship during this six-day period.
