Patient's question:
Doctor, I had sex around 10:00 PM on the 1st, and had sex both yesterday and today. We originally wanted to have a child, but we've decided to hold off for now. Can I take birth control pills?Doctor's answer:
I'm glad to explain the issue for you. Based on the situation you described, it is speculated that emergency contraception pills are still relatively effective for sexual activity in the next two days, but their effectiveness is reduced for the first sexual activity. If your ovulation period is on the first day, there is a possibility of pregnancy. This is because emergency contraception pills are effective when taken within 72 hours of unprotected sex, and the earlier they are taken, the better the effect.
