Had a harmony test Friday morning last week. Was told it would take 4-7 working days. It's only been 5 but I'm going out of my mind worrying about it as we came back as high risk. Would I be unreasonable to call the lab now and check when the results are likely to be back? Even when it hasn't been 7 days yet? I'm sick of checking my emails every 5 minutes but don't want to be a royal pita either...
