Did I screw up my glucose test??? Help...

So I had my glucose test last week and passed (yay!!!). But a friend of mine said that you're not supposed to walk around. And my husband and I took a tour of the birthing center. Did I throw off my test by walking around? I only want a positive if I'm due one. I don't want to be really negative and go untreated... Help! I sat for the first half an hour, walked around for 15-20 min, then sat for the last 10-15..
