I havent gotten my period in 2 months thanks to bith control, im not pregnant but a couple nights ago i had sex for the first time in about 3 months, i normally get small tears in my vagina from sex, but they never bleed. Its been two nights and i just got really bad brownish red discharge, and i was also bleeing a tiny bit during sex. I get the depo shot, could this have something to do with it? Has this happened to anyone?
