i'm 19. i was diagnosed with polycystic ovarian syndrome at the age of 13. I've been on a variety of bc since then. the one i'm currently using i've been on for over 6 months (nearly a year) with no problems. I had a cyst rupture 2 years ago and during the laparoscopy i was diagnosed with endometriosis which was treated with depo shots which put me in menopause for 6 months. I stopped those shots and started birth control in august of 08' and have been having regular periods since. i get regular preg. tests so i know that's not it.
