Patient's question:
I had my period on December 16th, met my ex-boyfriend on the 20th, worked from the 21st to the 24th, and started dating my current boyfriend after the 25th. Now I'm pregnant. My last period was on November 26th, but it came earlier this time. Could this child be my ex-boyfriend's?Doctor's answer:
The date of menopause is generally 14 days before the next menstrual period. After the ovum is released from the ovary, it can survive for 1-2 days in the fallopian tube, waiting for fertilization; male sperm can maintain its fertilizing ability in a woman's reproductive tract for 2-3 days. Sexual intercourse during the days before and after ovulation increases the likelihood of conception. For safety, the 5 days before ovulation, the day of ovulation, and the 4 days after ovulation are collectively referred to as the fertile window. Sexual intercourse during the fertile window increases the likelihood of conception. Based on the description, the child cannot be the ex-boyfriend's.
