I don't think they can tell you that you can't switch.. you always have that right to choose.
I'm seeing my bee dr at 29 weeks, its not to late and with something like a c-section you need to go where your most comfortable
That doctor might only deliver at that hospital, however, you can still switch and start seeing a new OB! ☺️
I switched obs like 4 months ago It is never to late to switch just find a new one and talk with her about your c section
Trust your gut. It’s never too late to switch until you’re actually in labor and even then you can request for a different OB on call. I would hardly say 28 weeks is too late either. I know a couple women who switched after 32 weeks.
