SOS Abnormally heavy and early period?

Masina • Miles and Journey’s Mommy 💜💙

Usually my period is light-regular and usually right on schedule. Well this cycle she showed up yesterday at 9dpo (5 days early) and it’s SUPER heavy. I don’t remember ever having a period this heavy. I can only leave a super tampon in like a hour and it’s full. What’s going on? Should I be worried?
