What does implantation spotting look like?

For the past two days I have had pink and light brown tinged cm when I wipe along with mild cramps that are sometimes achy, sometimes pinchy, and then sometimes no cramps at all. Not sure of dpo or when AF is due because my periods are irregular, but I think I ovulated around 10 days ago. I’m not having any of my other usual menstrual symptoms.

Did anyone here have implantation bleeding? If so, what did it look like?
