I wa should was called in less than 24hrs (and on a Sunday!) that I had it.
If your worried ring your community midwife I did for my last test (tested 3x as had gd with previous pregnancy) they usually are perfectly happy with you checking
I was told the same, no news is good news but they'd contact within 48 hours with results if they were positive or unclear 😊 You could always ring the hospital or midwife if you are anxious to know? I don't have the badger app where I am so not sure how it works but maybe the weekend can delay anything showing up on there?
