Spotting dates 🤔

I have a average 30 day cycle.

My last period was June 4th.

I started spotting on CD19, pink then went to brown and it was only when I wiped, it lasted for four days on and off and stopped for one day then very light brown spotting the day after then stopped.

I’m due on in 3 days.

Could this possibly be this implantation spotting that I’ve recently been hearing so much about?

I’m so new to all this and so confused.

I’ve never ever spotted like this before.

Thank you for your help 🙏🏼
