For the past three months I have been having a full period about every two weeks. Period for one week, a week and a half to two weeks off and then another period again. I have been regular my whole life.
This all started when I became sexually active again, it seems almost like every time I have sex, I start my period within the next few hours. I am a healthy 25 year old, and can not think of anything to explain this. Any help?
Thanks
Cyn
