Hi I'm abit confused! I've missed my period, I took a pregnancy test and it came up with a very faint positive line but then it dissappered? I took 3 more today the 1st was a very faint positive dissappered again 2nd 1 line negative 3rd the very faint positive line came up first then the control line but then the positive dissappered again! Why does it keep dissappering? Do I take it as pregnant or not pregnant? Please help thanks.
