I am four days late on my period and I lost my virginity about a week ago. The first time we had sex the condom broke but he did not realize it. After he finally noticed, he said he did not cum and that he had to pee the whole time and was holding it in. After he went to the bathroom he put on a new condom and we went at it again. This time the condom did not break and he also pulled out prior to ejaculation. Should i be worried about pregnancy?
