I have a situation. About 2 weeks ago I was on my last row of birth control pills which are the inactive pills. On my first day which is when I'm supposed to get my period I did not get it and instead I just got a brown discharge that lasted only for a few hours that day. Maybe 2 or 3 days after that I missed one of the inactive pills and had unprotected sex. After that day I had stopped taking my pills altogehter. A week later I had unprotected sex again while not on the pill. I want to know what my chances of being pregnant are. Last month I didn't get my period either I just had the brown discharge. The only other symptoms I have is an increase in appetite and I've been burping a lot, and have bad gas cramps that make me have to use the bathroom and a few days I can't seem to get out of bed. I REALLY NEED TO KNOW WHAT I SHOULD BE THINKING.
