Why do i sometimes get a light spotting after i have sex? is that normal? it's light pink and when i wipe a couple of times and then it goes away.

From the cervix: For some women the cervix, which is the part of the uterus at the top of the vagina, can have cells on it that are fragile. Meaning they can bleed a little when touched by the penis during intercourse. This is not a problem. However if you start experiencing pain or heavy bleeding with intercourse there might be a problem such as an infection or a growth so get it checked.
