Tiny bit of blood after wiping after sex had cin3 all clear now could he bumped my cervixs during sex? I'm on the pill im worried

Normal. The tiny bit of blood during or after intercourse can be normal. Hormones can make the cervix very touchy, and a small amount of bleeding is nothing to worry about. In addition, it is completely normal for your partner's penis to bump your cervix every time! The vagina is only 4 inches long on average when not in use, so this is definitely a normal occurrence.
