Is my mind getting the best of me? COMMENTS PLEASE!

Ok here's the scoop, I'm on CD 4 my period is usually right on time but I started 3 days early and it was really light. I might have used 8 regular tampons the whole time. It was also short by 1 day. I had watery cm mixed in also. (Only about half my tampon had blood but was soaked.) no smell or anything either. My overnight tampon sometimes leaks out when I get up first thing in the morning resulting in blood all in my panties and sometimes on my legs. This time on CD 2 I woke up to feeling like I had the normal over full tampon but when I stood it was just like water and my tampon had very little blood. (And no sex since the day before AF came) I don't wanna get my hopes up but could I be pregnant? I'm afraid to test. PLEASE COMMENT!
