So here's my story and confusion wrapped up in one.

I originally took my GD test while I was 28 weeks but due to my already terrible memory before being pregnant for the second time I forgot to get my blood drawn and left out the doctors office. Went back at now currently 30 weeks to take the test again and I failed. Now I'm up at three in the morning with work in 6 hrs wondering if it's too late to take the test and how being 30 weeks pregnant may effect my results since I was supposed to have the test done at 28 weeks and had to drink that super sugary drink back to back like that.

Any voices of reasoning out there?
