Gestational Diabetes

Hi, recently I failed my glucose test at NUH. They requested that I attend a class with a dietician on Thursday. May I know if any mummies from NUH experience this? I'd like to know the following : 1. is it a one time class or every week? 2. If we need to purchase the self monitoring kit, are we able to use one of our own if we already have it at home? Thank you!
