took two pregnancy tests yesterday, one in afternoon and one in morning (tesco). they were both negative within the development time. I was emptying my bin and the morning one has now turned into a positive line (obviousy after the development time), but the pm is still showing negative. does this mean im pregnant or is it common for tests to turn positive after a while

It could possibly be an evaporation line...

leave it a coiuple of days and test again! Have youmissed you period yet? When are you due on? x
