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 . 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 .
