Getting pregnant - Overweight

My husband and I are planning to start trying for a baby soon. I am currently overweight (5'10 - 215 lbs) and vey nervous about getting pregnant. I asked my OB about my weight and she let me know I needed to lose 30 pounds before even trying to have a baby. She said that I would be considered high risk from the start and need to drop as much weight as I can before. 
While I know I need to lose weight I also know that many women my size (or larger) have had healthy pregnancies and most importantly healthy babies. 
Would love to get some feedback on this topic... should I consider switching OBs? Or will I be told the same thing by others? 
I felt like I was already being shamed for my weight, instead of congratulated for wanting to start a family.
