Okay so I had sex on the 27th of October and that exact day I quit taking my birth control (the pill) and I had a week and like 3 days before I had my period pills which are a different color and now it’s November 12th and I haven’t started my period or anything at all I’ve been upset to my stomach a lot at night time that’s about it and had this discharge on November 10th could my cycle just be messed or what ? I may have had some withdrawal bleeding but it wasn’t a lot but I can’t remember
