I was 18 weeks pregnant with my last child to do the same exact thing you are. I wanted a doctor that would be there until the end. It was the best decision I could have made. It was an awesome labor and delivery with him. He came in at 3 am for me.
I have the same doc with this one too! I look forward to d day! Lol
I had to move to a different state right near the end of my pregnancy so i had to switch at 32 weeks! It was hard to find another midwife that i liked but after i did it went really smooth. All my previous information and test records were either faxed or emailed to my new midwife and i only had to take a few new blood tests that were required by the new state i moved to. I'm on my second pregnancy and still with the same midwife. If you decide to switch, it should go even easier for you!
If you don't like your doctor, it is your prerogative to switch. your deserve to feel comfortable and taken care of by your practitioner.
I did switch back to the OB that delivered my daughter. Its not that I didnt like the midwives I was seeing, but I just didnt trust them to manage my blood pressure and didn't trust them to take care of me the correct way if I were to get preeclampsia. plus being seen at an Army hospital, I was seeing a different person every appointment and I'd rather just have one person managing my medical care. But I did switch. Had my first appt on Friday with her and am glad I did. She remembered me like I have been seeing her for a long time.
