Gestational diabetes

Sooooo lately I've been having a lot of dizziness! And my dizziness hasn't been a result of moving to quickly or getting up to fast. It's been while sitting and while eating... One time while driving. So I've noticed since Saturday I've been having dizzy spells daily however today was the worst! I finally contacted my doctor and she believes it's my glucose. So I have to get my glucose testing done tomorrow 😪 I just hope everything is ok!
