I had unprotected sex the first of January. I could not afford the Plan B pill so I took 2 birth control pills the morning of, and 3 each day for the next 3 days .I followed directions I found online, not smart I know). I had only been off my regular period for a week and a half at the time of the unprotected sex. I had a period the next week after taking the BC pills. This month, 2 weeks earlier than I should have started, I had a slight period. I have tested twice withe negatives both times.Could I be pregnant?
