10 dpo Implantation Bleeding?

Katie

I am currently 10 dpo and woke up to this light spotting and cramping, as well as tender breasts. I am testing negative on a pregnancy test, but I’m confused because I am someone who typically has very regular 29 day cycles, and I never, ever start this early. I’m a little worried because I have experienced two miscarriages this past year, so I’m hoping this is either my period or implantation and not a sign of another early MC.
