Morning numbers

My morning numbers are really high still always 90-112 mostly on the higher side. I'm on glyrubin and I've been watching my diet. My obgyn said its just the way my insulin is working when it comes to the fasting numbers. He upped my medication but I still feel guilty and extremely fusturated with everything I eat I'm starving all day and just miserable. 31 weeks/ I just hope I have a healthy baby and I'm not doing anything wrong.
