Will I Pass My 28-week Glucose Screening In 7 Days If I Stop Smoking THC Now?

Hi, I’m 28 weeks pregnant and not a casual THC smoker but have been smoking very little every night for the past week & have my glucose test in 7 days, if I stop now could I pass my urine test? Or will the THC show up on my glucose test if not? I live in the state of Alabama. Thank you.
