2 Different Care Providers during Pregnancy

I was wondering if anyone has had experience with having 2 different care providers during their pregnancy? Recently, I've decided that I wanted to birth at a birthing center because the hospital I was planning to birth at has too many rules relating to COVID. I'm a FTM and the experience the hospital is offering isn't an ideal option considering if I test positive for COVID (we all know how reliable those tests actually are), then my fiance won't be allowed to birth with me. Something about that seemed off and not right. Can you imagine the anxiety of that and having to wait 15-20min for the results while in labor? I decided to try a different option and a birthing center that my insurance does cover came up, thankfully, and I began seeing them. The birthing center requested treatment documents from my OB GYN, however, this practice will not give them access, even with me signing the documents, unless I give complete care to them. I've never heard of such a thing. I still would like to have my regular prenantal appointments with my ob gyn, while planning to birth at the birthing center. I called my insurance company prior to the switch, asking if I'm allowed to have more than 1 doctor, and they said yes. However, it seems my OB GYN office will not release my medical records unless I switch care completely and that isn't what I want to do. I can only give birth at birthing center as long as I maintain a low risk, uncomplicated pregnancy. I'm 32w pregnant, and so far we are low risk. If anything changes, I'd like to deliver at the hospital, with the OB GYN I've been seeing most of my pregnancy. I was wondering if anyone has had any experience with this? Midwives will be treating me at the birthing center and legally, there are only a few things they are able to practice legally due to their restrictions which is another reason why I'd like to keep seeing my OB GYN on a regular basis. I have my OB GYN appointment tomorrow, so I'll go over this with them, but I hate confrontation, I get heavy anxiety over it like now, and don't want to be told I can't do something when indeed I can. I just hope it goes well. Anyone have a similar experience or any advice to share? Thanks in advance!
