Gestational Diabetes at 31 weeks

So I was diagnosed about 2 weeks ago with gestational diabetes and although my numbers weren’t really far from off, they were higher than where they should be. I saw a nurse and a dietician and they tell me to start with a different diet so everything went smooth for about a week. Now it seems like regardless of what I do, my fasting and my after breakfast blood sugar are always high . I’m gonna try to be more active. Right now, I’m just at home and don’t move a lot through the day . I was advised my fasting should be no higher than 94. It’s been anywhere between 95 and 105 this week. Maybe I’m eating too late. Any suggestions ?
