Implantation bleeding, period? Pp and confused !

Destiny

Started to spot on the 16th ( today being day 4. It’s 1:51am) it was nothing heavy just saw it when I wiped . It went from reddish to light pink to brown and then the next day went back to pink with discharge . On day 3 (yesterday) I went to pee after a nap and there was a tad bit more blood, red this time . Earlier in the day though I didn’t bleed at all . I thought it was a start of a period then at this point but when I went back to pee it wasn’t heavy and changed color again. I’m also cramping with this . Is this implantation bleeding or period ?

Last period I had was may 24th - 29th and my periods are messed up now after having my lo but to me this isn’t like the periods I’ve had before, even after having my baby .. this isnt like a period I’ve had
