Hi I'm upset right now.. I used to took pills but I get off with it. On may 30 I had sex with my boyfriend but I'm still on my pills on may 31 I stop taking pills .. on june 1 we have an intercourse. and he came inside me, 4days later I had this light spotting until the next day it became heavy, I was upset because the bleed is 2weeks early before my due date of my period . and today after my period I had this brown discharge . what could it be?
