Still using HPT's

I had a very, very faint positive early this month, which has gotten much darker over time, but I've still felt the urge to test every morning to see if my tests are getting darker. It's a ridiculous obsession considering I got my BFP 11/4ish and I'm still testing on 11/18! When my tests run out is when I think I'll stop, or when I see a heart beat, I guess. Am I the only one testing beyond confirmation?
