Okay so I'm usually very regular with my period and a couple of days before I felt different, the cramping I had didn't hurt but I was very aware of it, I took a clear blue pregnancy test which came up very faintly as positive, on Saturday I took a pink pregnancy test and it came up again with a faint line, on Sunday I took the cheap 99p ones and they were negative - still no period so yesterday I took another clear blue and although the line was faint it was the strongest one I've had yet but I took a digital one today and it said "not pregnant", I'm so confused, I was also using controls like dipping them in water and wee and comparing them and my wee samples had lines whereas they didn't - I'm 4 days late and still getting faint lines so I'm not sure what to think. any advice? x
