Glucose test

So i’m 35wks pregnant & never did the test so my dr ordered it & normally im someone with normal sugar levels, i’ll randomly get them checked & they’re usually around 70-90 even after ive had a lot of sugar but today i took the test & in just 5 minutes threw it up.... i was wondering if throwing up the drink is a sign i have GD????

I’m sure ive had really sugary starbucks drinks in the past so why would i throw this up & throw it up so quickly??? The drink they gave me was a clear sprite flavored one so its not like the drink tasted bad...
