Why do home pregnancy tests say to not read the result after 10 minutes? I got a Tesco one today, and after about 3 minutes of waiting it said negative. Then had a peek before I was about to bin it and there is a (slightly faint) positive. What is that all about?
I do remember a similar thing happening once before, and it turned out I was pregnant. I have irregular-ish periods, so technically I am testing about 4 days 'early'..
Any tips/stories/advice? Ta.
