Hello, I Am 7 And A Half Weeks Pregnant. My

Hello, I am 7 and a half weeks pregnant. My boyfirend and I recently had sex Saturday morning, 1/14/17. Since then I had light bleeding whenever i went to the restroom and cleaned myself. It never dripped or anything. Today after I woke up from a nap I went to use the restroom and I had blood on my underwear and there was a lot more when I went to clean myself. I'm not going to like I am very scared, but I'm also wondering if this is normal or not?
