Around May 11 I had sex with my boyfriend, and he ejaculated in me. It was 3 days before my period but I was on the 3rd pack when he did that, (still currently taking the Lutera pills) and I had only been 2 hours late on one pill at the beginning of the second pack. For my period, I had old blood come a day early but my actual period start the right day, it was still heavy and lasted the whole week. my next period is due next weekend. I have had headaches and a few stomach aches, breasts tender and worried to death. Am I pregnant??
