Hi everyone. I am also due for my AF on Tuesday - and I have been naughty and done a couple of tests which have both been negative so far. I used a fertile focus and know that I ovulated on 31/01. But I then got a very light bleed (not normal) 6 days later and nothing since. I was thinking it may have been an implantation bleed but so far tests have been negative and I am really confused. Has anyone else experienced an implantation bleed?
