Gestational diabetes

I failed my first hour ogtt by 0.3mmol and was told im diagnosed with GD. But is it true that mummies confirm will pre diabetes or type 2 diabetes in 3-6yrs? Im in my early 30s i cant imagine myself getting diabetes at such a young age. 😔 this pregnancy stressing me out #advicepls #firstmom #gdm #diabetes #firsttimemom
