Gestational Diabetes the next step

So MW has been testing for about 2 weeks now and is doing ok. She has scored below the limit after every meal, but is still scoring high on her morning scores. She is going in tomorrow to figure out what the next step is. She may end up on insulin or sugar control pills before bed. I guess the way the body works is that insulin is naturally suppressed over the night and into the morning. Because MW is already having issues controlling her blood sugar that extra suppression is pushing her over the limit. I will update again after her appointment tomorrow
