Patient's question:
I had my period seven days late last month and it was one day late this month. It's been 20 days since my period, but I haven't ovulated yet. What's going on?Doctor's answer:
The ovulation date of a woman is generally about 14 days before the next menstrual period. After the egg is released from the ovary, it can survive in the fallopian tube for 1-2 days, waiting for fertilization; male sperm can maintain fertilizing ability in a woman's reproductive tract for 2-3 days, so sexual intercourse during the days before and after ovulation is more likely to result in pregnancy.
