Implantation Bleeding

Husband and I have been TTC for two months now. I've also missed my period completely. I believe I'm experiencing some implantation bleeding, because it's started off as very light spotting and it's color is brown. Although today will make day 2 of the spotting, and it's gotten a little heavier, still brown though. Could this be my period, or implantation? I have no cramps.
