Midwife???

Racheal
I want to have a natural birth, in the hospital with someone who will let me do it my way. I want a midwife for that reason. But I also want to have all the proper tests done and ultrasounds at my appointments. How can I have it both ways?? and what should I be looking for?? I know different midwives have different levels of certification. Whatcha kind can do this for me??
