So here is the situation. My boyfriend and I had unprotected sex on 4/13. he waited till last minute to pull out He didn't cum inside of me but we are worried about pre-cum. I've been on the pill since September 2012 and I do take it every day. I got sick out of the blue on 4/21 and he jokingly said I am pregnant. I took a test on 4/22 and it was negative. I've been obsessing about it ever since. Should I be concerned about it since im on the pill?
