We have been ttc three years without success and today I am 17dpo. I did a SuperDrug test this afternoon because I heard they were the best and more reliable than clear blue and frer. When I first did it the second line came up faintly but by the time my bf got home it has disappeared. What did I do wrong? I'm positive it was there with colour but now is really quite faint to the point I think I'm imagining it. He took it apart because he said it was a scratch and now it's invalid. My breasts are still painful and I've got cramps still but no period at all.
