Gestational Diabetes

So I got a call today from my OB regarding the sugar test I took last week. It was a 220. Never had diabetes and it doesn't run in my family but I'm devastated. I have to have my bf test me 4 times a day because I won't be able to do it myself. Tomorrow I go to the diabetes center to learn more about this. I'm 27 weeks and anxious to learn what life will be like from now on. If you have this or know someone who has this, please comment on your experience. I'm just scared and don't know what to expect. Thanks ladies!
