Patient's question:
Doctor:Hello! If vaginal bleeding occurs after taking emergency contraception, how many days does it usually last? My period only ended on December 21, and I had sex in the morning on the 23rd. I took emergency contraception because the condom fell off, resulting in contraceptive failure. Will this affect my next period? If it does, will it come earlier or later? I am currently using "Kangfu Xiaoyan" (rectal medication). Will this affect the effectiveness of emergency contraception? Please answer my questions! Thank you!
Doctor's answer:
Hello, vaginal bleeding that occurs during the use of emergency contraception is called breakthrough bleeding. It may be caused by insufficient estrogen levels or an imbalance between estrogen and progesterone, leading to partial shedding of the endometrium. Generally, vaginal bleeding gradually stops within 3-5 days, and it should not exceed 10-15 days. If the amount of vaginal bleeding exceeds menstrual flow or the duration is prolonged, it is necessary to seek medical attention promptly. Emergency contraception can affect your menstrual cycle. If your period is delayed by more than 10 days, it may indicate menstrual irregularities. "Kangfu Xiaoyan" generally does not affect the efficacy of emergency contraception.
