Sugar making me sick

Anyone else have this problem? At the beginning when I had morning sickness, ANY sugar would make me sick and vomit. It went away for a bit in the second trimester. Now (third trimester) certain sugars make me nauseous again. I’ve asked multiple times and my doctors assure me that this has nothing to do with being a sign of gd. I test for that in a few days. Anyone else ever just not tolerate sugar while pregnant? Didn’t happen with my first!

Update: I do not have GD
