Patient's question:
Doctor, I would like to confirm my delivery date. My last menstrual period was on June 10th, and it ended on the 15th. On the 16th, when I went home, something unexpected happened, and I was forced by someone to confirm that there was no ejaculation. After the 20th, I have been with my boyfriend and haven’t taken any contraceptive measures, as we always wanted a child. On July 25th, I went to the hospital for a thorough check-up and found out I was seven weeks pregnant. I’m too afraid to tell my boyfriend about what happened again. I really want this child, but I’m worried it might be someone else’s. Can you help me?Doctor's answer:
Generally, the ovulation period is about 14 days before the next menstrual period. If your menstrual cycle is usually 28 to 30 days, then the ovulation period should be around June 24 to 26. If you had sex on June 16 after your period on June 10, it should be in the safe period. You conceived around July 25, about seven weeks pregnant. It's about 45 days since your last menstrual period. It's quite consistent. Because the estimated gestational age based on ultrasound is just an estimate and there will be a few days of error. So it should be your boyfriend's.
