    Conception can be more complicated than some people might think. Luckily, Flo’s here to answer the popular question, “how often should you have sex to get pregnant?”

    Pregnancy comes with a multitude of changes — physical, emotional, and behavioral. But the events leading up to it are sometimes just as tricky to navigate. Learn about the various factors that come into play, as well as how often you should have sex to conceive.

    Age and fertility

    There’s an undeniable biological link between a person’s age and reproductive fertility. Over time, childbearing potential naturally decreases. As such, the best age to successfully conceive and carry a baby to full term is 35 or younger. 

    Why is this? The female body is born with all the eggs it’s ever going to have. The normal aging process gradually lowers the number and quality of eggs.

    When is it time to conceive?

    There are roughly six days out of the month when the chances of getting pregnant are particularly high. Here’s a detailed breakdown of the menstrual cycle to help determine how often you should have sex to conceive:

    • Menstruation

    Think of your monthly period — when the body sheds the inner layer of the uterus (or endometrium) — as the first phase of the cycle. It lasts anywhere from three days to a full week. Progesterone and estrogen are stimulated to rebuild the endometrial lining, and although the likelihood of conception at this point is very low, it’s not impossible. 

    • Pre-ovulation

    Following the end of your period, fertility slowly returns to normal. The presence of vaginal discharge indicates that ovulation is about to occur, and there’s a good chance of pregnancy in this phase. That’s because sperm are capable of surviving inside the vagina for up to five days and can fertilize the egg once it’s finally released.
