Dr denial

Im 29 weeks today and I've been trying for the past week and a half to find a new Dr at this one clinic, but they have yet to call me back or answer. So, I called a different place today and they said since I'm 29 weeks they won't accept me as a new patient, but they won't refuse me in the hospital if I go into labor. I haven't seen my original dr in 2 months and in those 2 months my husband and I have been trying to pay our bill from them before making another appointment elsewhere. My reason for switching is that at place 1 they said they won't keep seeing me if I don't pay them $664 in full every month, even if I pay them in little incriments they won't see me and if I get on pregnancy medicaid they aren't accepting any of those patients. They got very threatening with me and my husband, so I refuse to go back to them. Looks like I'll be going the rest of my pregnancy with no dr if place 2 won't accept me either. I was so upset I started crying when the woman from place 3 said they wouldn't accept someone this far along.
