I don't know if I'm posting this in the right section, but my boyfriend and I had sex yesterday and when I went to clean myself, I had like a creamy white liquid and at first I thought it was cum. But then my boyfriend took the condom off and we filled it with a some water and nothing leaked out so we think it came from me. I'm on bc and I just started my new pack of pills three days ago after having a normal period. Is this normal?
