Menstrual

Ok so my monthly isn't due until 1-30-2019 but this past week (starting on 1-22-2019 I started spotting like literally only when I wipe and it was a brownish color the whole time sorry TMI) and now it stopped completely which I have NEVER had before. So my question is does this sound like implantation bleeding or something else.

I have also had 4 children and 1 miscarriage.
