Can someone please shed some light for me I took a Sainsbury's own test come up clear positive . Over the moon and as we all do buy more lol and they was a different brands to Sainsbury's own and they all come up negative . I'm so confused right now I have had no sign of my period and had clear discharge when I wipe also had backache and very moody at times . I've worked out to be around 3weeks 2days so very early on . Shall I wait another 2weeks then test again? Or contact my doctor? Please someone shed some light for me !!
