I'm 19+ years old, i've poly cystic ovary. I've had sex multiple times in last 1.5 months (protected and unprotected too, however, my partner is sure that he didn't cum/precum inside and I tested pregnancy 5 times, each time negative. I had homoeopathy, then regestrone, even after completing regestrone, i'm not having my periods. It's been 1.5 months i'm not having periods. I'm having symptoms but somehow i'm not bleeding.
