Question about gestational diabetes!!

So I failed my first glucose test at 23 weeks. It was 187. I was dumb and ate McDonald’s on the way to the appointment lol. I truly didn’t even think, I was just starving coming from work. I haven’t been able to take the 3 hour test due to the virus so my doctor just now (31 weeks) ordered me a kit and strips to test at home. I’m on day 2 now and my levels have been between 88-121 at the highest. I feel like I got a false positive because of what I ate last time (and I haven’t had McDonald’s since 😂). I’ve ate healthy during this pregnancy and only have gained 11 pounds. I just hate that I have to do these blood pricks for 2 weeks and 4x a day😭 Baby isn’t measuring big, as of Friday he’s right on his due date. I really don’t feel like I have GD, should I tell my doctor what I ate when I went in for the first test or just keep using these strips for 2 weeks?
