Patient's question:
Female, 24 years old. Took emergency contraception on June 29, had her period on July 5, had her second period on July 31, and her period ended on August 6. Had sexual intercourse, but it was just penetration without ejaculation. August 17 is expected to be the ovulation period, there was some spotting, and the flow was particularly heavy the past two days, taking five days to completely stop, like a normal period. I want to ask what the situation is—is it a side effect of the birth control pill, irregular menstruation, or something else?Doctor's answer:
On June 29th, after taking emergency contraception orally, I had my period on July 5th. This is a side effect of the contraceptive pill, which caused vaginal withdrawal bleeding. It proves that breastfeeding was successful. The next two instances of bleeding were due to menstrual irregularities caused by emergency contraception. Since emergency contraception contains high levels of estrogen and progesterone, it can disrupt the endocrine system and cause menstrual abnormalities. Generally, the body can fully recover within 2-3 months after stopping the medication. It is recommended not to engage in sexual activity when there is vaginal bleeding.
