Quoting It's so Fluffayy!:" She just said that she would continue prenatal care until I find a provider and that she couldn't deliver. ... [snip!] ... familys needs which can stress me during labor and I'll have a tough labor and if complications arise she can be held liable..."
Going by that thinking, she can be held liable for turning you away in your last month and that stressing you out and causing a complicated labor.
eta: ESPECIALLY if she didn't give you a referral to someone else, or help you find someone else.
