Patient's question:
Hello doctor, my menstrual cycle has always been irregular. My last period was on April 13. I had intercourse on May 2, and also on May 8, 9, and around May 16. Later, I became pregnant. On June 20, an ultrasound showed the fetus was 6 weeks and 2 days, with the estimated due date being February 11. I would like to ask which intercourse led to the pregnancy? Thank you!Doctor's answer:
If your menstrual cycle is normal at 30 days, ovulation occurs about 14 days before your next period, which is around day 16 of your menstrual cycle. Sperm can survive in the body for 2-3 days, so you should be pregnant for the first time.
