Can I Get Pregnant After Unprotected Sex During Ovulation? - Obstetrics and Gynecology

When it comes to the possibility of getting pregnant after unprotected sex during ovulation, there are several factors to consider. First, it's important to understand the timing of ovulation in relation to the menstrual cycle. Ovulation typically occurs about 14 days before the start of your next period. In your case, since your last menstrual period started on April 27 and lasted until May 2, ovulation likely occurred around May 12, which aligns with the date you had unprotected sex.

Having unprotected sex during your ovulation window does increase the likelihood of pregnancy because this is when an egg is released and available for fertilization. However, since you mentioned that there was no ejaculation inside you, the risk of pregnancy is somewhat reduced, but not eliminated entirely. Sperm can still be present in pre-ejaculate fluid, and sperm can survive in the female reproductive tract for up to five days, so there is still a chance of fertilization occurring if sperm were present.

You took emergency contraception (Plan B, known as "Ai Yi Le" in your case) within an hour after unprotected intercourse, which is a proactive step. Emergency contraceptive pills are most effective when taken as soon as possible after unprotected sex, ideally within 72 hours, but they can be taken up to five days after. The sooner you take it, the better your chances of preventing pregnancy.

The side effects you are experiencing, such as fatigue, are common after taking emergency contraception. These pills can cause hormonal changes in your body, leading to symptoms like nausea, fatigue, headaches, and changes in your menstrual cycle. It's important to remember that these side effects are temporary and should resolve within a few days.

As for your anxiety about the possibility of pregnancy, it is understandable to feel concerned, especially after an incident of unprotected sex. If your period is delayed by more than a week from when you expect it, it would be wise to take a home pregnancy test for reassurance. These tests are generally accurate and can help alleviate your worries.

In summary, while there is a possibility of pregnancy after unprotected sex during ovulation, taking emergency contraception significantly reduces that risk. Monitor your body for any changes, and if you have concerns or if your period is late, consider consulting with a healthcare provider for further guidance. They can provide you with additional information and support regarding your reproductive health and any further steps you may need to take.
