Glucose..... Might have blown it

Je

So they had me come in two weeks early to do my 2 hour glucose. I called Dr yesterday with dehydration concern. Well I guess doc was concerned with my symptoms and wanted me in today for the testing. I was told I could drink water during since there was no sugar, etc. Well just hit the one hour mark and the lab tech told me Im not suppose to even drink water. So I may have screwed it all up 😫.
