Advice on prenatal care

I was informed by my obgyn at 20 weeks pregnant they would no longer see me for my pregnancy because I wanted a vbac and they do not offer that even though the only reason I mentioned it was because one of the providers offered it to me. They said the decision is final and I have to go somewhere else. I’ve called around and been turned away due to me being further than 14 weeks pregnant. I have only had a dating scan to confirm my due date, I have also already had an early glucose test because of a slightly higher bmi (which I passed). I have not had an anatomy scan. What if I can’t find a new provider? Will I and baby be ok without prenatal care? What should I do?
