?tmi... I may be out

Karissa • Expecting #3 in September
So I started getting faint lines last Thursday and consider Sunday my BFP which is when AF was supposed to start, Today I had a strange feeling w cramps and when I went to the bathroom had quite a bit of fresh red blood. Still cramping and bleeding tonight but not as heavy as when it first started. Am I done did I lose it?? Just don't know how to feel about this, never had anything like it in my first two pregnancies. I've been taking it easy all day is there anything else I should be doing, anyone ever have similar situation?
