Posted the other day with a test pic and a lovely lady tweaked it for me and there was the faintest of faint faint lines there. that was 4 days before af was due (a clear blue test) and i've done three really cheap tests since and i don't know what i see :( af was due today and i've had what i thought was implantation bleeding for two days then it stopped. this was a cheap test i did tonight but i think it's negative :( any thoughts? i've tried to tweak it but i've got line eyes! did one this morning too and that had nothing there! should i wait to try another clear blue test would that make any difference?
