Period question

Stormi
My periods happen around the same time but never exact date. They normally are light and last 7 days. Well my last one I started out spotting a little then I would bleed threw a tampon in half a hour. It would be dripping down my legs like crazy. (Tmi sorry) and it lasted for 10 days! It wasn't a miss carriage or anything but Amy ideas? That period started early and was February 25
