Did that "holy crap, can I do this" moment hit you yet?

I'm 37 weeks today and was at my weekly dr appointment I'm already 3 centimeters dialated and cervix is fully ripe .... OB said I'll schedule you for an appointment a week from today, but I won't be surprised if I don't see you because you've delivered. My due date isn't until 8/14. The moment just kind of hit me - WOW so excited but scared, and also, trying not to get my hopes up that I'll deliver early, knowing myself I'll be jinxed and be a week late ...
