TMI PHOTO Bleeding and confused

Anyone with any type of experience pertaining to this can please comment.

I had sex (semi protected and now the outcomes) the 7th of November while my projected ovulation was the 9th. Between the 9th and now, I have been having period like cramps.

I just went to the bathroom and am bleeding. However, my period isn’t due for any other week, which it hits perfectly on or one or two days past.

Implantation bleeding or just period?

It was more pink the first time I checked but now it’s dissipating a little.
