Need help finding a gastric bypass friendly OB/Gyn for pregnancy

I am finding out that I am 8 weeks pregnant, have been having some problems, put on bedrest for a week due to bleeding and cramping.... I would like to have an OB/GYN that is familiar with the vitamin deficiency's that we face due to the surgery and the best way to go about it. If anyone has a name, I would surely appreciate it... Thank you so much

I would call Dr. Brady at Good Sam in Cincinnati. He is high risk and my daughters both go to him. He is so darling and is a great Dr. My girls love him and congratulations on your new bundle of joy, Cindy
