Heavy flow problem

I’ve always had a super heavy flow. And I’m not talking like, I need to change a pad every hour. I’m talking about filling a super or ultra sized tampon every 30-50 minutes. Wearing both a pad AND a tampon if I can’t be within 45 minutes of a bathroom. Going through half a gif box of pads in a few days. Usually at school, it’s a pain to be excused every class period (ha) to use the bathroom and it impacts track practice. Are there any way I could possibly lighten it??
