GD diagnosis

I’m 28 weeks, first apt for this new diagnosis is next week with the dietitian and then one week from that appt is the one with the high risk doctor.

I know nothing about this as this was a shock for me to be diagnosed with, just wondering if it’s true that they let you continue your usual diet for a week while testing your blood sugars before they give you a new diet?

What should I be expecting here and is it ok if I continue eating the way I was until my appointment? I’m just nervous and overwhelmed. I didn’t really have a bad diet before, I’d give in to cravings here and there so I just got unlucky here with getting GD. Idc what I have to do to help me and baby, just wondering what to expect from those that have done this before!
