Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? Does birth control pills have an effect of causing amenorrhea?Doctor's answer:
Because the main component of birth control pills is levonorgestrel, it generally does not cause amenorrhea after use. However, it can significantly affect the normal menstrual cycle. After normal use, withdrawal bleeding typically occurs again within about a week. Even if withdrawal bleeding does not occur again, it will still have a certain impact on the original menstrual cycle. Therefore, there is no need to worry too much about your current situation—just wait a little longer.
