PLEASE ANDWER WHAT YOU THINK!!! 
I had a of blood in my discharge when I believe to have been ovulation about 7-8 day ago I have had unprotected intercourse almost everyday since then, about 3 days ago I had a bit of abdominal cramping. And now I have a thick milky discharge which I normally don't get. I have been feeling so tired and getting headaches. I read up online and thinking maybe I might be pregnant?
