33 days late bleed

Bronnie • 22, fiancé who we were trying for a baby cheated so now I'm single 👌🏼 live in England. Music and tattoos 👌🏼
I'm 33 days late but I've just started bleeding. It's really really light I'm usually heavy no period symptoms apart from belly feels tight but I don't usually have that symptom. Do you think it's period or spotting?
