Obgyn

I haven’t seen my regular obgyn for 2 years well now that I am pregnant for the 3rd time I need to get in to see him. While i was pregnant with my second I had a really high risk pregnancy I suffered from a sub chronic hematoma & I also suffered from anti kell. But my main concern is idk if I want the same doctor. He was nice but I just want a doctor that’s more informative. Should I go with the same doctor or switch to a new one ?
