My boyfriend and I had sex early in the day and we didn't realize the condom broke so, naturally, we just continued on. He pulled out before he ejaculated. Then we had sex again later that day, and a condom broke again. I took plan b about 32 hours later and I was supposed to get my period 6 days later but I still have not and I am very very scared. My symptoms were vomiting and body aches. Could I be pregnant?
