Patient's question:
My girlfriend is supposed to ovulate on December 18th, but we had sex on the 25th and she has had her period every day since. Now her period hasn't come yet. What could be the reason? Could it be that she is delayed because of the recent exam stress? Thank you!Doctor's answer:
Menstruation usually comes 14 days after ovulation. But your girlfriend "who was supposed to ovulate on December 18th" doesn't necessarily ovulate on that day. Excessive stress from exams can also affect the menstrual cycle.
