OB/GYN Drama !!

So today I had my 20 week Anatomy Scan and my Ob says baby Looks perfect and I'm perfect actually lost a pound since last month. ( total gain of 2pounds). Next we get on the topic of my birth preferences, I told her Wanted a natural unmedicated birth no epidural and she turns her head sideways and says "Why?"  I explained I think I can do it naturally and would like to move around during MY labor and I can't do that with an epidural, then I said many women have been having babies for years without right ? , she say "Yeah and many of them died." WTF!!! As if this isn't enough then she proceeds to tell me that pitocin is the exact same as the NATURAL drug oxytocin that our bodies release. I told her "ehh I don't think they are" she insisted they were. So on the way out I asked if I could switch to a different OB (their office has 5) I was told no. So Needless to say I will be making an appointment for a widwife consult tomorrow.
