GDM and Blood Sugars

Hey everyone, so each of my pregnancies I have been diagnosed with gestational diabetes. First was diet controlled, second was diet controlled until about 32 weeks and then was on insulin 🙄. This one has been diet controlled just fine so far. Staying within carb allowances, I honestly haven't tried anything new just because thins have been going well with what I have eaten. Until now. The last few days, specifically with post lunch and dinner readings, my sugar readings have been elevated. Not with EVERY one, but nearly. I cried, feeling discouraged, and not understanding why. So I made calls and let my OB and endocrinologist know and I guess we will see what they want to do. I will be 36 weeks tomorrow, but now just terrified to eat anything. Anyone else noticing spikes in their readings?

Also wanted to add, these high readings I recheck 20mins to and hour later and they drop significantly. Like 140 initially and then 20 minutes later down to 97. What is going on 😭
