Could this be Implantation Bleeding?

CD28. Cycle length has varied over the past few months, from short cycles to long cycles. I did not use OPKs this cycle as our stores were out, so I cannot confirm when my LH surge was. Usually when I get my period I have intense menstrual cramping for a day prior and when it comes, it’s usually not light at all. I have not had any cramping. Does this look lien implantation bleeding? What are your thoughts?

Please don’t make me feel stupid for asking this, I am new to all of this and I’m just trying to get educated through others’ experiences.
