Patient's question:
Doctor:Hello.
My period always comes 7-9 days earlier, lasting for 7 days. It started on December 17th and ended on the 23rd. On the evening of the 25th, I had sexual intercourse with my boyfriend. Is this within the safe period? Do I need to take emergency contraception?
This is my fifth time having sexual intercourse, but the next day, I experience small spots of blood. What could be the reason for this? Additionally, every time we have sex, there is a very large amount of discharge with a slight fishy odor. I had a routine test for vaginal discharge, and there were no abnormalities. What could be causing this?
Doctor's answer:
Hello: The safe period refers to the days when a woman with a regular menstrual cycle is least likely to conceive. Counting 14 days backward from the day before the next menstrual period marks the ovulation day. The 10-day period before and after ovulation (5 days before and 4 days after) is considered the fertile window. Any other time outside this window is considered the safe period. However, the safe period is not entirely foolproof, as various factors (such as stress, illness, medication, and environmental conditions) can affect a woman's ovulation. If you do not plan to conceive in the near future, it is best to use effective contraception during sexual activity to avoid unintended pregnancy.
