Do I Need To Be Concerned?

I was in the ER for the 2nd time in 2 weeks for serve dehydration and excessive vomiting. They diagnosed me with hyperemesis gravidarum. I called my obgyn to try and get in but due to insurance I have to have a nurses conference first. I had that scheduled for Wednesday. They called me today to see how I was doing. I told them how sick I have been and how my liver enzymes were incredibly high from what the ER said. I’m getting extremely concerned because they worked me in tomorrow when they said last week my first appointment to see the doctor would be the middle of December. Someone put my mind at ease?!
