what the gestational diabetes 😑

Sooooo I failed my one hour glucose test with flying colors, now I have to go take the three hour one tomorrow. My dr said he wouldn't be surprised if I fail that one too because my fluid level is extremely high and that is related to GD. I am so frustrated, I've been eating healthy and trying to be as active as I can. I didn't have this when I was pregnant with my son, so I'm not sure why I would have it now. Anyways sorry just needed to rant over this for a minute. Anyone else going through this?
