I am on YAZ Birth Control, and take every pill when I am supposed to. Except this month, I took one pill about 6 hours late (because I fell asleep). Me and my boyfriend are sexually active, but he always uses a condom. We have not had sex a lot lately, but we did about a week or so before my period was supposed to start. I started having a light brown/pink discharge the day I was supposed to start my period (yesterday) and it has continued into today. It is very very light. I usually have a very normal period. Is my period going to start? Am I just late because of still getting used to the birth control? I only started it about 4 months ago. Could this be pregnancy? Please help. Thanks!

Yes you could be, most likely no, but no birth control even when used properly is 100 percent, so it can happen
