Period helppo

So I ovulated on 7th july. I’m saying this based on the stretchy clear Cm on the day which I have got a pic off. On the Saturday I started bleeding which is making me really confused whether it was just normal spotting mid cycle or implantation. I know implantation cannot happen so quickly but I checked on google for implantation calculator and it says based on the dates of my last period I would ovulate on 4th july and start implantation on anyday starting 10th july if that makes sense.

It’s all so confusing so hope I make sense. The bleeding started on the Saturday and ended on Monday. Tuesday was just very light brown spotting with Cm but veryy light. I’m just confused on whether to count it as an early period??? My original period is due in 2 days
