Could I still have a chance for my BFP?!?

Carrie
AF is due tomorrow and I tested today and got a BFN shouldn't hcg levels be up by now?? feeling discouraged. I did have some bleeding a week before AF which I thought it was IB because I didn't seem like a normal AF but now that I got a BFN I'm not to sure if it was IB but instead a light AF... :/
