I have taken a few tests, being that I’m over 2 days late on my period. Which is not normal. My periods are typically very predictable. I took 2 blue dye tests at 1 day late and got two very faint positives. Then Yesterday morning and this morning, I have gotten negative red dye tests. However, it seems when I was doing the last red dye test, is when I finally experienced implantation bleeding. It was ever so slight, pink, and has not continued. But until that happens the hormone (hcg) can be too low to be detected. So I’ve read. So if I take another one tomorrow, will I finally be able to get a positive? I’m VERY impatient! I just want to know!!!
