I need a little guidance..

Hi there! Sorry for the tmi picture but I desperately need help. I went to the restroom earlier to find this.. I am 2 weeks out from my next period, and ive had a period (2 weeks ago) between the last time i had sex (about a month ago) and now. I am on the combined pill and have been for 6 years.. which has given me an INCREDIBLY regular period schedule. I take my pill as intended so why am I bleeding like this? Could it be implantation bleeding even though i’ve had a period? Or am I just randomly breakthrough bleeding?

bleeding?
