Is The Heavy Discharge During Periods Related To Hormones?

HELLO I AM 22 YEARS OLD AS OF MARCH. I HAVE BEEN ON MY PERIOD FOR 19 DAY NOW. THE FIRST COUPLE OF DAY IT WAS LIGHT THEN IT GOT A LITTLE HEAVY JUST LIKE A NORMAL PERIOD. THE LAST TWO DAY MY PERIOD HAS GOTTEN HEAVIER. IM STARTING TO GET A LITTLE WORRIED. I STARTED THINKING IT WAS HORMONAL DUE TO ALL THE STRESS.
