Glucose test! 🙄😭

As of now i’m only 6wks, but i’m high risk & have had 3 losses so my dr wants me to do the glucose test twice! once at 11wks & then again later on. I’m actually pretty scared to do it because i don’t want to feel shaky or lightheaded/dizzy and i was told a lot of people felt that way after! Any tips? And was it horrible for you? i also heard you can ask to do it with jelly beans?
