I think I'm 9 DPO and I have some mild cramping in my abdomen. I also noticed that there's more CM and it looks like a bit of spotting (dark brown - but very little - more like a skid mark . . .hehe sorry if TMI). I did not have any spotting with my prev. pregnancy so I have nothing to compare this to. My biggest clue right now is increased CM - does anyone know what to make of this? Is there a chance it's a sign of implantation?
