Just got back from the doctor.. Apparently because I had a blood transfusion about 11 months ago with the delivery of my second daughter, I am now RH positive, and really just don't like not knowing what is going to happen and having to have all this extra concern...I am a nervous wreck and can't help but freak out and on top of all that. My doctor(whom I love very much) is having her practice closed because of budget cuts and I would have to go to a not so nice part of town to see her.... Oh and she also thinks I have something called Ptyalism. I make too much saliva and that's why I keep throwing up. UGH I'm mad and sad all in one!!!!!! Any mamas have any positive stories or advice about RH?
