Gestational Diabetes Help

AB

This is my second baby and I was diagnosed with GD. My numbers were high for the 1 and 3 hour test. My doctor told me to eat as I normally would for the first few days so they could see where I need to make diet changes. All my numbers are within normal range after meals even fast food and having some soda. At night, my numbers are lower than what they should be. Which makes sense to me now since I usually feel bad in the evenings. It’s making me question if I even have GD. I’ve made no changes to how I eat and everything is coming back in normal range. I am measuring 3 weeks ahead. Has anyone had an experience like this? I’m ok with the diagnosis but this just seems odd to me.
