Random bleeding!

Lauren
So last night my boyfriend and I had sex and noticed there was a ton of blood. I'm not on my period, I am not cramping, I wasn't expecting this what so ever...just random blood. My period was two weeks ago and is over and done with and shouldn't be back now. Now today I am not bleeding nor bleeding... I fully examined myself..there's no cut or anything in that nature. Just trying to figure out wihy I had random bleeding.... Can someone please help???
