I would try to relax as much as possible about the reduced movements, as the previous commenter was correct in saying that the bigger the baby gets, the less room they have to move and less movement is to be expected. However, I would do what you can to get a new provider for the birth. It is very important not only that you be comfortable with and trust whoever is delivering your child, but they need to listen to you and hear your concerns as well.
I think that you need to refuse to see that particular Dr. they can not force you to if you decline them. You need and deserve understanding and compassion and if they can't give it to you you need to ask for another Dr. and report the situation to the office manager.
I'm so sorry this is happening. Your feeling should Akeaus be taking into play when possible and right now it is.
I would suggest taking somebody with you for your next apt who can get angry and pushy for you so...you can try and keep calm.
Also I found my insurance was amazing helping me, I called and asked what other OB's I could use and they gave me 3 options. It might be worth calling. Your OB should make you feel calm and relaxed not upset.
Can I ask why your last OB (who you liked) was removed from your case?
I didn't realise how badly the last birth affected me mentally until I had reduced movements 2 weeks ago and now I'm worried sick, even more so since my app yesterday, surely how I'm feeling should be taken into consideration
