So i usually take my birth control (microgestin 1/20) every night somewhere between 8 and 9 at night. Tuesday night I had unprotected sex and he finished inside of me, right after finishing, i remembered i hadn't taken my medicine. This was at about 12:15 am. I took it right then.. Now about a week later, I started having cramps like I was about to start my period but instead its sort of like a brown liquidy discharge.. I guess like spotting. Does this mean I am pregnant?? Should I stop taking my pills and test to see if I'm pregnant?
