Does anyone have any tips to pass gestational diabetes test?

I failed first 1 hour test, have to go back in for 3 hour test.

I was reading that apparently it’s best to go in after fasting, not having sugar, walking, and drinking lots of water before

Before the test this morning I didn’t know any of that, so had toast with peanut butter and jelly bc it was fast which I never have! And was trying not to drink a ton of water bc I have to use the bathroom so often and was in the car for awhile. So I think that definitely did not help 😕

So I plan on doing the above to help my results for 3 hour testing, does anyone else have any suggestions?
