I'm very worried about you. You need to call the doctor now---new doctor or not! Call the office and tell them how sick you are and demand that he see you right away. I used to work for a dentist---and I know doctors ALWAYS have time to work emergencies in their schedule.
This cannot be good for the baby. You have got to think about that.
When I was pregnant, I got a horrible stomach virus and the doctor prescribed pheneregan (not sure of spelling) suppositories. That calmed my stomach down immediately ---and knocked me out (it makes you very drowsy.) Maybe they could give you one or 2 of these to stop the vomiting.
If you don't do something, you are going to end up dehydrated (if you're not already.) You've got to be losing potassium and other vital minerals. And this could put the baby in jeapordy.
Call the doctor! This is not normal morning sickness!
