Never been pregnant, not pregnant, no thyroid problems, no pituitary problems. I've been to a normal doctor, and OB/GYN, and a female chest appendage surgeon and no one knows whats wrong. They said it could be birth control, so I went off it and went on something else for a few months, and it still happened. But I want to know WHY it started, its not like I changed my sex life or birth control to make it happen...Anyone know whats up?
