so about two days ago I had what I suspected to be implantation bleeding. spotting with a little brown discharge and it only lasted a few hours. I took a blue dye test last night and it looked to be negative of course. I decided to take a pink dye this afternoon and there was a faint second line so I just waiting and at the 5 minute mark the line was there clear as day my phone camera sucks but it's pink and faint. my question is it possible to have even a faint positive so soon after what MAY have been implantation
