Anyone feel like they aren't pregnant?

Lindzie • No, the hospital will provide a dictionary; bring a thesaurus.
I'm 6 weeks, got a positive test from the doctor, and I'm visiting my OB tomorrow for the first time. I have nausea, tender breasts, I frequently urinate, but for some reason I just cannot convince myself that I'm actually pregnant! I told my husband and it felt like a lie! Anybody else feeling this way?
