Choosing obgyn

Hello all-
I found out over the weekend that I am expecting a little one June 2016- I am having a hard time deciding on an obgyn. We currently live in the suburbs but plan on moving back to the city come June (I didn't plan the timing that's when our lease is up) should i go see an obgyn by my current residence now and then switch in the very near future to a doctor in the city where I will eventually be giving birth? My main thing is getting all the blood work & everything else that is needed done ASAP!! Thoughts? Thank you much in advance!!
