Period or implantation?

On day 2 of my “period” which was 4 days late

Yesterday seemed a Tad heavier but that may have just been because I was only using a liner.... this is only the second pad I’ve used all day and I only changed the other due to it starting to smell it wouldn’t have even been this much.....

implantation or period being a bloody weirdo? What do you ladies think?

I don’t want to waste another pregnancy test if im just being obsessive and crazy...
