Changing doctors

L

It saddens me I thought my pcp referred me to a good ob...I'm 12 weeks and I dont feel like we are a fit I feel like the care I have received is subpar to say the least this past weekend after been blown off for a week by the ob I ended up in the emergency room the nurse there told me I should seriously consider changing doctors...my question is has anyone done that is it hard to do? What happens? TIA
