Does anyone have gestational diabetes? How does it affect you? I failed my test so I have a 3 hour test this week to do but I was wondering if anyone has it and what you have to do to keep your levels normal, my family line is full of diabetes and so it knew it might catch up to me. This it's our 3rd pregnanacy and it's been really stressful and nd scary for me. Do any of you have to treat with insulin? Does it hurt the baby to have it etc. I'm just kinda scared.
