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. To get a better sense of when you’re ovulating, chart your basal body temperature and your cervical mucus. You might also use an over-the-counter ovulation predictor kit to check for hormonal changes in your urine before ovulation.
Have sex often: Your odds of getting pregnant are best when you have sex 1 to 2 days before you ovulate. But cycles vary in length, and some women are irregular or have miscalculated their cycle. Sperm can survive in a woman’s body for up to 5 days. To hedge your bet, have sex frequently starting 3 days before ovulation and continuing for 2 to 3 days after you think you’ve ovulated.
Lie low after sex? It has long been believed that you should stay in bed for at least 15 minutes after sex to give sperm a chance to reach the egg. However, recent studies found no evidence to back up this claim.
