Yucky sexđŸ˜«

I’m on a pill which stops my periods and I just have irregular light bleeding very rarely. I haven’t had it for months but I was blessed with it today, more specifically tonight whilst having sex with my boyfriend. We didn’t notice until after and I went to the toilet embarrassed and came back and he pulled faces and said something like “well that’s disgusting”, making me feel really gross and bad. I said I obviously wouldn’t have had sex with him if I’d have known I was bleeding and he just pulled another face. I don’t know what to say to him now but how he went about it just annoyed me. Should I bring it up or just leave it?
