Pregnancy brain

I was supposed to do my glucose tolerance test 3 weeks ago and totally forgot. Now I'm 28 weeks and I see my doctor soon. Do you think she will totally get annoyed with me? I haven't had any symptoms so I think I would've passed anyways because I check my blood sugar weekly and I've actually had lower or normal blood sugars. I heard your OB can kick you out of their practice if you don't do certain tests. It slipped my mind honestly. Has anyone taken the test later than 28 weeks?
