Maybe it's just a large tumor?

I am beginning now (7 days past due) to wonder if there is actually a baby or has this really been some cruel joke?! When someone has not slept for more then 1.5 hours at a time in about three weeks their sense of logic and judgement quickly start deteriorating. This is why I am really starting to question if he is ever coming... seriously!!! The Dr. promises by next weekend we will be parents one way or another....but I'm not holding my breath about it- at this point I'm not believing it till I see it!
