I didn't pass my 1hr glucose test 🤷🤷

I mean I'm 330 pounds and diabetes run in my family so it's not a huge surprise... I mean I lost 65 just to get pregnant and I know I'm still in the 300's but I worked my ass off so I am very proud of that achievement :) anyways they are making me take a 3hr glucose test this Saturday which I already know I am going to fail... Which is no big deal I mean the doctors are there to help maintain my sugar and I'm gonna need all the help I can get what did you guys do to maintain your blood sugar? Did you have any complications? Did you have to get a C-section? (Really don't want that) I just want a healthy and happy baby! Any tips from other plus size/obese moms???
