How do you know its implantation bleeding

So 2 days ago I had thick egg white discharge.

I get it pretty heavily (enough to soak through my leggings) every time I ovulate.

Then yesterday I randomly bled. It was all day, but ONLY YESTERDAY. it was light bleeding but everytime I wiped and was Brownish blood, no pink or red.

Now today absolutely no bleeding or spotting at all.

Is this typical of implantation ? Or is it just spotting.

Never in my life have I spotted between periods though....
