So I had sex unprotected 5 days before my period i have had my period I just spoted I was on birth control but missed 2days before unprotected sex I took three pills birth control pill that night thinking I was fine and I also had unprotected sex again but didn't take my pills the next day.. I took a test it was negative I've been moody stressed have been cramping and not period still so I don't know if I'm pregnant or not.
