Swim notices that when she uses for a few weekends in a row or more it really messes up her cycle...like she'll get her period two weeks early or late and then it will either last like a day or for weeks at a time. Swim never has this problem when she is totally clean. Also, if dope is causing this effect while swim is on birth control, which is supposed to make your cycle completely regular, does it mean the dope is negating the birth control (sure hope not)?
Any of the ladies in here know what is going on/ have experienced this?
