Thank you for all your comments and support on my last post. The spotting I wrote about had stopped by midday and hasn't returned. I called St. Mungo's at MM's request, and the on-call nurse said over three-fourths of their IVF patients have some kind of spotting in the first trimester and that they would not be concerned unless it was bright red bleeding saturating a pad an hour.
I continue to "feel pregnant": unusually tired, most-of-the-day nausea, food aversions. So I am hoping that all is well.
This morning is my first OB appointment and ultrasound. Despite my annoyance with my doctor's office, after I calmed down and regained my perspective, I concluded that I'd be likely to run into the same types of scheduling mistakes at any clinic, so I'm not going to find a new doctor. My two closest friends who've been pregnant in the past few years both used this practice and were very satisfied (and one of those friends had a lot of complications and got to know every doctor in the group).
I will post later today about the results of the ultrasound. I am mentally prepared for everything from an empty uterus or no heartbeats to two yolk sacs, fetal poles and heartbeats. We shall see.
