hi was after some advice please, im 4 days late and have taken 3 tests and all 3 have come back with a very faint line, a couple you ciuld hardly see unless you put them up towards the light so im really hoping it means a BFP but im just not sure, how long do you think i should leave it before i phone the doctors to get a bloodtest done. When ive done tests before with my other 2 dd the line came up clear straight away
