How Soon After Sex Can I Get Pregnant?

Contrary to popular belief, pregnancy does not occur immediately after unprotected sex. There’s a specific window in a woman’s cycle when pregnancy can occur, and understanding this can help you plan or prevent pregnancy.

The Fertilization Window

For pregnancy to occur, a woman must ovulate, meaning an egg is released from the ovary into the fallopian tubes. This egg needs to be fertilized by sperm within 12-24 hours of being released. Sperm can reach the egg within 30 minutes after sex, but sperm can also survive inside a woman’s body for up to 3-5 days. Therefore, there is a five-day window during each cycle when pregnancy can happen.

From Fertilization to Pregnancy

After an egg is fertilized, it travels to the uterus and implants itself. This implantation triggers the production of hCG, the hormone that pregnancy tests detect. For the most accurate results, take a pregnancy test on or after the first day of your missed period. Testing too early can result in a false negative due to low levels of hCG.

Understanding Your Cycle

The average cycle is 28 days, but if your periods are irregular, it may be hard to tell when ovulation occurs. In irregular cycles, ovulation could happen as early as day 11 or later. If your periods are irregular, it’s best to wait about two weeks after unprotected sex to take a pregnancy test for more reliable results.
