New to GD

Hi Mamas!  So, I have PCOS and was already on Metformin twice a day prior to getting pregnant.  My NP had me do my glucose test early, and I found out yesterday that I do have gestational diabetes.  I am 14 weeks.  To be honest, I was SO sick up until 13 weeks that I hardly ate anything, let alone take my Metformin like I should have.  So, now I am walking an hour a day and doing my best with the Metformin.  I go to meet the dietician next week.  Yesterday, I felt SO awful after eating (protein and carbs), I'm wondering if I should ask for something more than Metformin to get better glucose control?  Because before I eat/ a few hours after I feel fine, so I am pretty sure it is related to my blood sugar.  Also, does GD make you high risk?  Thanks!
