Is it my period or implantation bleeding? Bleed for 4days and it was light and brown a little light red but mostly brown? Had sex on all fertile days

In brief: Could be, but

Breakthrough is more likely.
'implantation bleeding' is mostly internet fad, it's over-rated in importance. It's not common to see and is usually not 'implantation' but breakthrough bleeding.
