Currently freaking out....

Im currently almost 38 weeks pregnant. I had hypoglycemia before pregnancy and I checked my sugar for a few weeks Around 28 weeks (instead of glucose test) and all of my levels were completely normal... so doc cleared me of GD. Tonight I ate supper super late like 9:30PM the supper was a cheese burger and cheese fries with unsweet tea... I checked my sugar 2 hours after and it’s 153. It’s never been high like this... if anything it’s always on the lower end of normal. Like 90 or even 80 2hours after meals. I’m super anxious and haven’t had much sleep so could that be causing it to be high?? I know sometimes my anxiety causes my blood sugar to drop... I just want to make sure my baby is okay from one high reading.... I can’t help but worry 😭😭
