Hello. As the title says, I had what might have been implantation spotting 4 days ago (6 days after DD) and have been feeling pulling and cramps since. Did a clear blue early this morning that showed a faint line straight away which became darker blue over 20mins. As I peed in a cup, I rushed to shop and bought a clear blue digital (6 day early one) which showed not pregnant but the wee was about 1.5hrs old at this point. I know they are notorious for evap lines, but would it have showed a faint line within timeframe??
