Does this look like the start of AF or implantation bleeding?

I have PCOS. I have one or two visits from AF a year, roughly. Woke up to this this morning, and it's been so long since ive had a natural AF (was on birth control for 2 years, got off nov 2017) that i dont even know whats normal anymore! TTC (kind of) so no precautions are being used. What do you guys think?
