No, I did it 28w in all pregnancies. Do you have a family history of diabetes? Are you considered overweight by your Dr? They could just be being cautious.

Seems like my 1st pregnancy they tested early like maybe 16 weeks but this time they're saying 28 weeks. I'm probably gonna ask to be tested sooner since I had a bad episode yesterday, 21 weeks. I think it depends on the doc and your history. Also it's the placenta that throws glucose off so maybe it has to be bigger to start causing the issue.

I had to do it at 6 weeks as well.

I did one at 10 weeks and have another at 28 weeks. There’s a history of diabetes in my family and my mom is a type 2 diabetic and was diagnosed prior to pregnancy

Yes they said since diabetes runs in my family and I started out a little heavier and I’m glad the did test me early since I do have it and was diagnosed at 8 weeks and now I’m 34 weeks
