So I had sex with my boyfriend and I don't take any birth control. He didn't come at all. And that was the 3rd of April. The last day of my period was the 27 of March. I've been waiting for my period. And I usually cramp a day before and the next I get my period but this month I started cramping 3 days before my usual period and I have blood on the pad but it's only a bit. I usually have a heavy flow. The blood is light pink kinda brown.
