Tiny bit of blood after wiping after sex had cin3 all clear now could he bumped my cervixs during sex ? im 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.
