BFN! Ttc on clomid! Could I still be preg.

A
Ok so I am probably just grasping at false hope but I need advice. I took a clear blue digital test which I read needs 50 MCG of HCG in order to read positive. I tested at 7:20am the last time I perfect was 3:45 after peeong just about every hour could I still be pregnant? I just really felt like I was this month and don't want to believe the negative test.
