Hey guys! 
I'm 29&1 today and I found out yesterday that I've got gestational diabetes. They said my blood pre-drink was fine but afterwards it went really high. I'm already on consultant care because of high-risk of pre-eclampsia. What did gestational diabetes mean for you? How did it change your pregnancy?
