first, i hope you are feeling better and that the original issue is resolved? did you figure out what was going on? it is just incredible and unacceptable to have to deal with such bullsh*t when you have a real life, sensitive medical situation affecting your pregnancy. how can docs not get that? for a doc to add stress to a stressful medical situation is just messed up. plain and simple. "it doesn't really matter"? really? that is a shocking and terrible thing to say. sorry you have to deal with this. undeniably an unnecessary stress, but hopefully you can just take your time and find a new practice without a lot of headache. better to know sooner than later, i guess. hang in there, erin!
oh, and on the P4, i can't remember where, but i've read on these boards that you can order your own blood work. i'll try to see if i can find the link, but if so, you can test your P4 as much as you like!
