3 hour glucose test...

Okay guys... so I am only 14 weeks, but my glucose levels were high last week. They said the cutoff was 135 and I was 146. I did have a VERY high carb snack before going to the doctor office (I caved to a Taco Bell craving), so I am hoping it’s related to that... my OB said she thinks it could possibly be. Anyways, what I am nervous about is having 4 pokes 😭😭 someone tell me it doesn’t hurt more when they poke you in the same spot an hour later😭😭 also, I’m still having morning sickness... so for me to not eat anything from 10pm tonight until it’s over tomorrow around 2.... I’m going to be so sick. What happens if I can’t keep the glucose drink down? Someone please ease my mind.
