I 18F and my bf 18M, just had sex and he finished inside with a condom on for the first time. When he pulled out, we noticed a thick white kinda foamy consistency on the top of the condom and at the base of his penis. I have a huge fear of getting pregnant, so I was (still am) super scared. He said that it wasn't his cum since the condom was skin tight and there were no holes (we examined the condom). Ig it's just nerves, but I wasn't convinced. We both looked up different things, and one page said that it is possible for his cum to leak at the top of the condom, but I saw a few other things saying that it could be my discharge? That female discharge can turn like that during sex? I've never had thick white foamy-ish discharge before, so that's another reason why I'm so scared.
I'm thinking of taking a plan B just in case, but my bf says he's 100% sure that I don't need to cuz what we saw wasn't his cum. I'm still scared. I don't want to take a plan b because of all the side effects I've heard of, but I also do want to take it cuz of the risk of what I saw might have been cum.
