Three hr Glucose test

So I did my 1h glucose i had tuna salad probably around 4/5 in the morning I couldn’t eat nothing with sugar so that’s what I found that I thought it didn’t have any, so three bits in iforgot sweet relish was in there so I took the test that morning failed it by two points and then my dr said I gotta take the three hr test which I’m considering refusing because they half to poke me 4times and I do not do well with needles the first time I almost fainted . The nurse called and scheduled me for the three he test what shot I do?
