I have just done a clearblue test, af not due till Monday (I think - last bleed was v light for one day on Feb 13th, previous af was mid Jan, horrendously heavy and doc thinks may have been early m/c) and got a really really faint vertical line. I don't think I am imagining it, there is definitely something there.
Do the lines get darker the further on you get? Has anyone ever had a faint vertical which turned out not to be a BFP?
Don't know whether to get excited yet. Have read other threads and know everyone says "a line is a line", can anything other than a pg give you a faint line?
