Brown discharge for 3 days, pregnant?

Hi all,

So my cycles are between 30/31 days.

On day 22th i started seeing brown discharge, i never had it like this before. It was only with whipping.

And on day 24th it stopped.

today after sex i had a tiny bit of blood again. it was only on 2 wipes. if this is implantation bleeding when can i test?.

does anyone recognize this type of blood?
