Like an idiot, didn't read the instructions until after I'd used it. It says to hold in your pee stream/pot of wee for 5 seconds only, I must have left it there a good 20-30 seconds.
So, question is - could that cause a false positive? Everything I've read suggests false positives are really unlikely, and an internet budget one this morning looked possibly like a squinter but I messed that up by dropping water on the test screen. But it wasn't particularly concentrated wee either (about 7pm) and I can't quite trust it because it's so clear. I was slightly ashamed of myself for even bothering to test so late in the day with a hastily purchased frer rather than waiting til morning.
Go on, tell me to chill out and test again in the morning properly like a sane person.
