Heavy heavy period

I can’t work while I am on my period I get so heavy I leak my pants all the time while I am standing I have big blood clots the 2-3 day I last 7 days

What’s a natural way to make my period light

And also I use overnight pads and I still leak them in the day and night

I hold my crotch when I go to the restroom when I am at home . Honestly it’s so heavy I can’t even be at work while I am on my period

I noticed heavy periods after my 3rd baby

I really don’t want to be on birth control tho is this bad or normal
