22 weeks pregnant gained 28 pounds!!

I had a doctors appointment today and my doctor told me that my weight gain is out of control. I'm 5'8" and weighed 200 lbs before getting pregnant. I knew I had gained some but I didn't think it was that much!! I feel so embarrassed, I don't eat like crazy but I do get hungry. he gave me a paper for a diet that's basically for high blood sugar. my glucose test came back normal when I was about 12 weeks pregnant and he wants to do another one when I'm 28 weeks. has anyone else gone through that type of weight gain or does anyone have any healthy meal and snack ideas? I'm always snacking on fresh vegetables but I do have my occasional chocolate bar 😔
