Oh I just did the same thing! At 14 weeks I made the decision to change - I'm expecting twins & feared I'd have they early, etc and the hospital I was going to deliver at didn't have a NICU, so if there were issues they would send the babies to another hospital while I was still stuck recovering at the 1st hospital.. without the babies. This was completely not an option for me - so I had to switch.
I was never in love with my OB/GYN, so it didn't break my heart to leave them to begin with, but when I called to tell them I was transferring (and I was honest about why...I needed a NICU!) they were pretty rude, so I'm VERY glad I made the switch. I think Moms have instincts like no one else in the world...and when you feel its right..its right.
I've only had on appt with my new dr, but I can firmly say I know I made the right choice! They were so kind and welcoming & made me feel at home...very unlike my old office!
Good luck to you & your new dr!
