Moving while pregnant

Kasha
My husband and I have decided that we are moving. His commute is well over an hour, we will have outgrown our current house when the twins arrive, and making the move would allow us to be significantly closer to family. 
We are getting lots of pressure from both of our mothers to move before the babies arrive (currently 22w6d). My primary concern is that my dr's and hospital would be over an hour away making weekly appts tedious. Now I am wondering if moving with twins who could be in the NICU would be worse (Baby B has some health concerns that are being closely monitored) than moving while pregnant. 
Anyone experience a similar experience or have any insight? I plan on bringing this up at my next MFM appointment in 2 weeks.
