Postpartum period?

I was 9 weeks postpartum on Saturday. Since about Tuesday I have been having what is like watery discharge but it is pink. Then around Friday it was more red and had tiny specks of blood in it. It now this morning is more clear but had tiny bits of blood in it. Could it have been my period despite it not being like actual blood or is it still maybe postpartum bleeding (which stopped at 7 and a half weeks)

I got the depo injection the day I gave birth and my periods before were heavy, lasting around 6 to 7 days. I am also experiencing the same kind of cramping I usually did when on my monthly.

Sorry if tmi
