So im 14dpo at the minute, I've take 2 first response early results pregnancy tests both negative and a clear blue rapid detection also negative! I took a clear blue digital today (14 dpo, 3 days until expected period) and it came back not pregnant, so I did what you shouldn't do and opened the test, please remember I opened it as soon as the result came up on screen so it wasn't left sitting around for hours, and there's clearly 2 lines on the strip? Both blue? Can anyone help or suggest anything? X
