Implantation Bleeding?

I’ve had this three times in the last 36 hours but it’s only when I wipe after peeing- there is zero flow to it. The second time it was slightly lighter but this time it’s slightly darker but less of it. Could this be implantation bleeding? I know some say it’s pink some say it’s brown and I’ve had a hard time finding people with brown examples, so what do y’all think?

Also- I don’t get a regular period at all so tracking ovulation is near impossible and I can’t really say track my cycle so I have no clue how many dpo I am or when my period is “supposed” to start. But I’ve been sexually active almost every day the last two weeks- minus three days, not consistent. Prayers this is something good! Any comments helps so much!
