May 24th, i had sex with my boyfriend. He was inside me for less than a minute and he did not ejaculate. I'm worried that there was a pre- but he said there wasn't because he peed before. So i took a morning after pill two days after we did it. I took 4 pills every 12 hours but only for 2 1/2 days. Two weeks had passed i didnt feel any symptoms. Until now, i started throwing up every heavy meal that i ate and im always constipated so i took a laxative and the outcome is i pooped but with blood! I think its blood!! WHAT IS HAPPENING TO ME. And today is june 7th, my period is late!
