I had preeclampsia with my first & while technically being overweight raises your chances for that, it's also often one of those "first time mom" things. It hasn't returned in my subsequent pregnancies. I have always turned down the GD test (I don't like the unrealistic way it's done, but I'm odd enough that I turn down 99% of the tests--all I have done is the initial bloodwork & then the Group-B Strep test towards the end, & the last time I didn't even have that done).
Congratulations! You can certainly have a healthy pregnancy. Take care of yourself, and try to make each bite as healthy as you can manage. Walk for exercise when you can. I really recommend
The Birth Book or
The Pregnancy Book by William & Martha Sears; they're the only pregnancy books I know of that let on that you don't have to take each & every test.
The Birth Book has a marvellous rundown of the tests, what they're supposed to do, and their drawbacks & advantages, & similar info on the various forms of pain management & relief that'll be available to you in labor.
Whatever else, the number one rule for a good pregnancy is: Ask questions of your care provider. Any question, no matter how small the issue. It's part of their job to answer stuff.
