Doctor or midwife?


Hi, it's my first pregnancy and I got an appointment set for my first visit with an obgyn but i happen to be unprepared and didn't do my research of doctors so they assigned me one and it's a midwife. Should I try and get a doctor to take care of me? I mean aren't midwifes kind of nurses that know stuff about delivery but have no medical school, can't administer drugs and so on?

I'm worried!
