Concerned about period... TMI

Hello, my period was late and now for the past few days I have had this bleeding- it varies between this colour, brown and a light pink. It’s often not enough to make it onto my pad but when I wipe it’s there.

My periods are usually very very heavy and dark red so I’m confused on what is happening?

I have been trying to conceive but assumed that I didn’t succeed due to my period.
