Ugh!!! I hate GD!

Amy • Single mommy to a handsome boy and currently expecting baby #2!
So at my last ob appt. Baby is 10oz...which I looked it up and is supposed to weigh somewhere in the 5oz range. My glucose levels have been soooo high! Like 180's high. I can't stomach a lot of foods and so yes, carbs are a go to. But I stay completely away from sugars and processed sugars. No sweets or nothing. I just don't know what else to do! Nurse said if my numbers are high this week, I'll go on medicine and if they don't get down with the pill, I'll have to take the shots. Please God don't make me take the shots!! I can't give them to myself and I live with my brother and my 3 year old son! So yeah! But does anyone know if they give metformin for this stuff? I have PCOS and was taking it prior to finding out I was pregnant. I have no problem taking it again. But not sure if I can or not or if it's safe. Any pointers?? Ideas? Anything???
