My lpd was 25sept . I went through test on 24 oct i,e one day prior my due date & it showed faint line on T spot too. then on 26 i again went through same test but i came out negative. but this time the kit i used was unwrapped a day ago ( i just unwrapped it to compare the strip with the results of 24 oct & kept it back in foil) but not used it. was this negative because of the unwrapping of the kit but if it was invalid it might not have shown any line but C line was coloured clearly. Now it's 27 oct & i hv missed my periods too but not gone through any test in last 24 hours. Does all this mean i m pregnant & when should I go for retest . Please read carefully to sincerely answer.
