Okay so I usually have anywhere from a 28-30 day cycle. I'm on the birth control ortho tri cyclen. I missed one pill on the 11th and the other on the 12th. My period is suppose to start on 5/24 but I started bleeding on 5/13 ( the day after the missed pills) and it lasted till the 16th. My last period was 4/27 to 4/30. I had unprotected sex on both days I missed the pills and the days before. Is there any way I could be pregnant? What was the bleeding?
