I have been taking the same oral contraceptive for almost a year and a half now. I have changed it a lot before but this one seems to work just fine for me. My period has been on time and regular since i have been on this oral contraceptive. My boyfriend and i had sex without a condom about a month ago. No missed period, it came like normal. However, this month my period was about a week and a half earlier than normal. Its more than spotting but less than a usual period. I was wondering if that is anything to worry about.

Could i be pregnant?
