Yesterday was af due date, and after having v v v v sore (.)(.)'s i (and i am so sorry for TMI) went to the the toilet and had a tiny smidge of blood.... so i thought oh ok here comes af... and nada???? haven't even had a tiny bit more. I have heard of implantation bleed but don't understand it very well. I have tested but bfn, but after looking at peeonastick.com it says that i wouldn't show bfp till at least 2-4 days after bleed and even that would have to be a sensitive test eg 25miu. Has anyone been through/going through/know of this??
