Ok so I had my period on the 16 which lasted 7 days like usual. About a week later I had unprotected sex with my boyfriend and he did not pull out. The werid part is two days after that I had some light pink discharge only when I wiped which lasted a couple hours and then stopped. Doed anyone know what that means? It has never happened before and its werid to me lol and yesterday and today I have had these cramps like right under my rib cage! Just everyonce in a while!
