Insulin during pregnancy

Hello, any mums or mums-to-be has or is under insulin for high GDM readings? Able to share how was the insulin journey and also coping with GDM? Also those that has given birth prior to GDM, any side defects on either mum or baby because of insulin? This is my first pregnancy and was diagnosed with GDM at 28 weeks (now almost 32 weeks) started insulin 1 week ago and heard different stories about insulin, which then doctor/nurses repeated assure that it doesn't affect baby... #1stimemom #advicepls
