Glucose test- at 8 weeks

Daelyn • Happily married and mama to Finn Charlton + Ellis Jameson👦🏼👶🏼💕

I have my first appt on Monday, but they want me to come in today to do the 1 hr glucose test because my little man born last year was 9.5 lbs at birth. I'm SOOO nauseous all the time and rarely eating because I just can't stomach it. I just know that getting my blood drawn and drinking that drink today is going to be horrible. Can I opt out of doing the glucose test?
