Gosh...I'm almost 15 weeks and some days I still don't believe I'm pregnant. It still feels weird to even hear the words come out of my mouth! Maybe it's because I've been waiting so long and I'm a FTM but wow... it just doesn't feel real yet for me most days.
I hear ya! Almost like you're waiting for the other shoe to drop, for the bad to catch up and happen.
... I have a kid who is about to turn six, and that still strikes me as bizarre.
