Spotting,Implantation?

Sunshine

I had sex on ovulation day or day before I think,wasn’t particularly tracking. 6 days later I had dark brown bleed after sex which was there with the body excreting the left over semen, then there was nothing. At first thought period then realized was too early then started counting back. Today 5 day to next period I had pinkish bleed after coming from gym in morning but only when I wiped and nothing since, the color is different to my usual start of period.

I don’t know what to make of these bleeds and color! Could it be implantation? Ready to conceive but put it aside cause it just wasn’t happening so now wondering?
