My norm is something along the lines of:
6am do test, see nothing, put it in the bin after 10 mins.
6.20am, get it out of bin, hold it up to light, see nothing, put it in bin.
7.00am get it out of bin, hold it up to light again, see nothing, squint from all different angles, see a 'maybe' line (which is completely imaginary!) put it on the side of the sink cabinet thing.
7.10am squint at all angles under the light, see nothing, put it in the bin.
8.30am get it out of the bin have a good ol'd squint again, take test apart, see nothing, put it in bin.
12 noon, get it out of the bin, squint at it again, see nothing.
12.10pm Do another test, repeat above.
6.30pm do another test, repeat above.
6.30 (next day) do a test repeat of yesterday.
and again, and again, and again until period comes!!
