I have just used the Clearblue plus POAS thing and the instructions said to wait 3 mins before reading the result but as soon as I looked at it, the result window had a cross and the control window had the line in it. I am testing a couple of days after AF due. I have looked at it 50 times and looks exactly like the positive result in the picture but as it happened practically before I'd stopped peeing and def not 3 mins wait, can it be real?? It hasn't changed in the last 10 mins btw not that I'm checking it obsessively.
