Diagnosed with GD at 29 weeks.

Hello mummies! I just finished my test and I was tested with GD. I’m on my 29 weeks and the baby is already 1.3 kilos. Can I check if anyone of had GD at third trimester, how did you overcome it? What foods did u eat and exercise did u do? I’m very worried on my baby 😢😢😢😢#firstbaby
