um...you need to be a little more specific so I'm not sure how to answer this. But if you're asking what it is, it is just when the egg implants itself on the uterine wall and it may cause slight spotting. You may notice this around the time your period is supposed to start. It should only be enough bleeding to see it when you wipe or a little spot in your panties.

I had that with my son. I felt like I was going to start my period, it looked like I was going to start my period, I even put on a tampon that morning before work. Just stopped after a bit of light spotting.
