Trying to conceive can require a lot of planning, knowledge, and an understanding of your body and general human biology. It’s not exactly sexy, but it is crucial if you are hoping to get pregnant.


Conception is a tale as old as time (literally)—sperm meets egg and implants in the uterine lining, then gestates and grows for about nine months, and then you give birth. But let’s rewind and start at the very beginning.

Fundamental Building Blocks for Pregnancy

To conceive “naturally” or by way of penetrative sex, a person who is born with ovaries and a uterus (among other body parts) must ovulate. Then, sperm must be introduced into the “female” reproductive system (often via ejaculation from a penis). However, there’s more to this process. At the most basic level, the person providing the egg must ovulate, and the person contributing sperm must have healthy sperm that have good motility.[1]


According to the American College of Obstetricians and Gynecologists (ACOG), ovulation most commonly happens 14 days before the first day of your period, regardless of the length of your menstrual cycle.[2]

One way to track ovulation is by using a calendar, though there are also other methods, such as through a number of smartphone applications. Reliable, but not foolproof, methods of knowing when you are ovulating include [2]:

  • Physical sensations (cramps or other PMS-like symptoms)
  • Cervical mucus, which “peaks 1 to 2 days before ovulation”
  • An over-the-counter ovulation test
  • Menstrual cycle tracking

When to Have Sex to Conceive

You do not have to have sex at the exact moment that you ovulate to get pregnant, nor do you have to have sex every day to get pregnant. ACOG posits that, due to the fact that sperm lives for as long as five days in a woman's body, and an egg lives for up to 24 hours after ovulation, the fertility window is up to 6 days per cycle. This means that having sex five days prior to ovulation, or even up to one day later, could lead to pregnancy.[2]

According to ACOG, in order to have the best chance of conceiving, “research suggests you should have sex every day or every other day during this six-day window.”[2]

How Long Does it Take to Get Pregnant After Sex?

There is no one correct answer to this question. Conception isn’t accomplished every time people have sex, and even when they do, many factors contribute to and hinder the timeline of conception (for example, sperm motility).

Fertility Concerns

If you and your partner are struggling to conceive or have concerns about getting pregnant, talk to a trusted health care provider as they are an excellent resource for education and medical intervention. In this day and age, reproductive technology is sophisticated and provides many options for those who are trying to conceive.[3]


In conclusion, "How long does it take to get pregnant after sex?" is a question with a nuanced answer. By understanding the various factors at play, managing expectations, and seeking professional advice when needed, you can navigate this journey with informed optimism.
