Questioning my period

Okay guys. So I started on the 19th. Had light bleeding. Never enough to soak through a tampon for the 19th and 20th, had a little spot of blood on my tamp this morning from over night, so putting a pad on, now there's nothing on my pad, but just brownish pinkish when I wipe? I cramped like crazy on the day I started & My periods usually last at least 4 days... Not two... Can anyone relate, or does it sound like it's not a period? I need guidance 😂
