Help! Lol

So I had some light bleeding for one day on the day I was supposed to start my period. I had spotting when I wiped for 3 days following. Light cramping that has still continues into what should be day 7 of my cycle. My periods are typically 4 days long and typically need a tampon for 3 days and light for last. I guess I'm just asking if anyone else has experienced something similar and what was the outcome?
