Recommend your OB. I am currently going to Roswell OB/GYN and this may seem petty, but they are sticklers for certain things. With my son, I was in another state and loved my OB, she did what ever she could to make sure I was happy and re-assured. I had a decent amount of u/s with my son and I'm looking for a doctor that will give me more than the average amount of u/s's. Another thing about my OB is that she only delivers at Northside Atlanta, I'd prefer something a little closer.
