I had my 3 hour glucose test yesterday and I'm still waiting for my results. My one hour test I felt so tired, got a headache and my stomach was so upset during the hour and after, this time I felt good during the 3 hours of testing but got an instant headache after eating and drinking water. I had to call off work this morning because I still had a headache. I'm afraid I didnt pass the test with the awful headache I got. Has anyone had similar symptoms after the test but still passed? My first test I got a 134 and the cut off was 130 so I wasnt that high.
