Implantation Bleeding

I know it’s not a very common thing but i spoke with two friends because i felt like something was off. i attached a picture of my cycle for reference. two years ago i stopped getting the depo and it only took 6 months to get back to a regular cycle but i took the depo again recently and started ovulating again before it was done. he didn’t pull out somewhere between the 23-25th and there was a time or two after ovulation but in fertile days he did pull out. my ovulation spotting was the 27-28th i believe and on the 4th i started having this spotting. it lasted till yesterday i believe. it’s only when i wipe but it’s thick, mucusy & brown/pink. this is my second ovulation.

thoughts?
