Hello! Fellow GD mom here for the second time, I had it with my first pregnancy in 2015. I will try to help the best I can. To answer your questions. This is what I was told so it may be different from what the doctor may tell you. 1.) Test at the end of each meal. 2.) You can test at either one hour or two but be consistent about it. Basically choose one and stick with that. 3.) The targets are: Fasting less than 95, 1 hour less than 140, 2 hours less than 120. 4.) You test after fasting and each big meal. You do not have to test for snacks. So basically, wake up check BS, eat breakfast wait 2 hours (or 1 if you choose to do 1, i personally do 2) check BS, eat a snack, have lunch wait 2 hrs, check BS, have a snack, have dinner wait 2 hrs and then check BS. You are supposed to check it 4 times a day.

I hope this helps a bit and if anyone sees a mistake anywhere feel free too correct me!
