I feel like you've already said everything you need to say to her to create boundaries, and if you two start talking again and she asks you anything else about your pregnancy or birth care, you are perfectly within your rights to simply refuse to answer her questions.
It sounds to me like there's a lot more going on with her than just not agreeing with your choices. My best friend is a pediatrician and she doesn't take it as a personal attack on her that I home birthed and I don't vaccinate my daughter, for pete's sake! There are PLENTY of people who work in health care that respect other people's choices and don't think they know everything just because they are health professionals.
It sounds to me like she is unhappy about being on bed rest, probably scared of losing her baby, possibly regretting her choice of health care providers but is unable to admit it to herself, and may be jealous of you for being in better health and better circumstances and/or projecting her anger and hurt about her situation onto you.
I'm not sure from what you posted who decided you weren't talking to each other or what the circumstances were there, but what do you think about reaching out to her, letting you know you you respect her career choices and want to help her through this difficult time, but you still will not discuss your pregnancy with her?

We get it all out in the open, kiss and make up, we love each other like crazy and after defending my choice a bit I would let the matter drop and figure out a way we could still enjoy our pregnancies together. My SIL and I were pregnant last time together, her 2nd, my third and though she is a RN who planned a hospital birth with epidural and any other interventions that may come her way and I planned a homebirth for the 2nd time (ended up having to scrap that due to high blood pressure just hours before labor began and had a natural midwife only hospital birth), we were totally supportive of each other and had a lot of fun!
