Strange Period or Implantation Bleeding?

Sorry if this picture is a little much and warning that this may be TMI.. but I wanted to get thoughts on what everyone thinks this is? About 5 days ago I had brown discharge that lasted the day, maybe a bit into the next. And then yesterday (two days before my expected period) I had a browny + light pink color when I wiped which I assumed was the start of an early period because of the pink looking

blood. All of my tampons yesterday came out brown and way less covered than normal. And today I’ve only had the occasional brown when wiping. Then this evening I went to the bathroom and wiped and had this brownish blob come out? Bear in mind, I have HEAVY period. And they go from pink to full red heavy blood within a couple of hours. Just wanted to get opinions from other women before I think this is implantation bleeding or an infection. I have no other signs of infection and only have one sexual partner. Any thoughts? THANK YOU!
