High Numbers

I was diagnosed about three weeks ago and I am 31 weeks along. I'm so far just diet controlled and I think my numbers are pretty good. I get a high number 2 or 3 times a week. I really cant wait to be able to eat what I want, some days its a struggle. How often does your doctor allow a highish number and still think you're doing ok? So far during the week, while I work my numbers are great because I'm on a schedule and I only pack things I know will be ok. The weekends are my biggest problem with doing errands and lately I've had a lot of baby and bridal showers and weddings. my two biggest concerns are my baby's health and size. I'm so afraid of having an over 8.5 pound baby. Does anyone else have this worry, or what are your experiences with baby size?
