My boyfriend and I had sex about a month ago, and I am not on birth control but we did use a condom, I was also on my period, AND he pulled out with the condom on. I have all of my regular PMS symptoms, and I’m cramping yesterday and today, but I still haven’t got my period. My period was due yesterday. I feel like it’s near to impossible that I’m pregnant, but I’m so scared. Should I be ?
