I DEFINITELY want a new doctor!

I have to know: Is it too much to ask for a doctor to look at a patients' file before you have your first appointment? I mean, I have been in that office about 5 times in the past couple of weeks for endless blood tests and ultrasounds that have shown nothing (as you all know!) and he doesn't even know how far along I am?! Seriously, he was going off of the assumption that I was 10 1/2 weeks along, even though I was just barely over 6 weeks. It's just so frustrating to know that this practice either has a serious communication breakdown, or that the specific doctor I met with is absolutely incompetent. I can't help but be incredibly picky, and I don't want to be a bitch. But this is my first pregnancy, and the doctor is such a key factor in all of this that I want someone that I feel really comfortable with to guide me through the process! So far, I really haven't had even one positive experience at this office, and that is not a good sign.
