help?!?!

So me and my bf had sex two days ago and he was wearing a condom but when we finished I checked and I had white stuff all over my vagina and he said that the condom wasn't broken and that all the cum stayed in the condom. So Idk if it was from me or him cuz I didn't feel like I orgasmed or anything. And it looked a little bit more white than what cum normally looks like. So is it possible it was from me or is it possible it could have came out the condom?
