Anyone with GD

Lili • Mommy to a beautiful four year old red head boy and two pug babies... happily married nd expecting baby no 2!
So I failed my 2 hour glucose test.. now I need to go for another sugar intolerance test. Because my sugar is very high. They will draw 4 tubes of blood from me tomorrow in the course of the day. Anyone else had to do this nd if you have GD is it quite serious? TIA XXX
