Period or Implantation ?

Skylar

Period is due today but yesterday starting at 2:30 or so my discharge was brown and mucusy. This morning I checked again and it was still the brown color and then about an hour or so ago I checked it and this is what it’s looking like and was a small clump of old blood in bottom of toilet. I read that some people have implantation like this so I’m just so confused. Him and I did it on the 5th and 11th this month so it sort of adds up in a way.
