Emergency Contraception: Can You Get Pregnant After Unprotected Sex? - Obstetrics and Gynecology

Emergency contraceptive pill


Having unprotected intercourse during ovulation, even without ejaculation, carries a risk of pregnancy.
Taking emergency contraception immediately after the encounter can reduce this risk significantly.
If you had unprotected intercourse again the next morning, but also took emergency contraception within 2-3 hours, the likelihood of pregnancy is still low, but not entirely eliminated.
It's important to consult with a healthcare provider for personalized advice and to discuss any concerns regarding potential pregnancy.

Hello, the questioner: There is a possibility of pregnancy even if ejaculation has not occurred during intercourse, as pre-ejaculatory fluid may contain sperm.
Additionally, the effectiveness of emergency contraception is not 100%, with a failure rate of about 3%.
It is recommended to check for pregnancy if your period is more than a week late.
Thank you! Wishing you peace and health.

More Info


When it comes to the risk of pregnancy after unprotected sex, especially during the ovulation period, there are several important factors to consider. In your case, you mentioned having unprotected sex during your ovulation period without ejaculation inside, and you took emergency contraception (EC) shortly after.
Firstly, it's important to understand how emergency contraception works. Emergency contraceptive pills (ECPs), such as Plan B or Ella, are designed to prevent pregnancy primarily by delaying ovulation. If taken within 72 hours (Plan B) or up to 120 hours (Ella) after unprotected intercourse, they can significantly reduce the risk of pregnancy. Since you took the pill immediately after the encounter, you have taken a proactive step to minimize your risk.

The timing of your sexual activity is crucial. Since you were in your ovulation period, the likelihood of pregnancy is higher if sperm is present. However, since you did not ejaculate inside, the risk is reduced. Sperm can survive in the female reproductive tract for up to five days, but without direct ejaculation, the chances of sperm reaching the egg are lower.

Taking emergency contraception as soon as possible after unprotected sex is key to its effectiveness. You mentioned that you took the pill shortly after both instances of unprotected sex, which is a good practice. The sooner you take the EC, the more effective it is at preventing ovulation and, consequently, pregnancy.

Now, regarding your concern about the possibility of pregnancy: while there is always a risk associated with unprotected sex, the combination of your timing (during ovulation) and the immediate use of emergency contraception significantly lowers that risk. If you are still concerned about the possibility of being pregnant, the best course of action is to wait until your next expected menstrual period. If your period is late, you should take a pregnancy test for confirmation.

It's also worth noting that if you experience any unusual symptoms or have concerns about your reproductive health, consulting a healthcare provider is advisable. They can provide personalized advice and support based on your specific situation.

In summary, while there is a risk of pregnancy after unprotected sex, your immediate use of emergency contraception significantly reduces that risk. If you have further concerns or if your period is delayed, consider taking a pregnancy test or consulting with a healthcare professional for further guidance.
