First time for 3hr glucose test... Nervous!

This is my 3rd pregnancy and the first time I have ever failed the 1hr glucose test... I got Monday morning at 715am for my 3hr and I am so nervous. Type 2 diabetes runs in my family and all my life I have been doing everything to keep that as far away from me as possible... Now, with the threat of gestational diabetes I am scared all my efforts are in vain... Praying for normal results Monday.
