Bleeding through super+ tampons

I used to only wear pads for like 4 years, and then I switched to tampons. I love tampons so much better, but the first 2-3 days of my period are so heavy, I bleed through super+ tampons. I really don’t want to wear a pad or a panty liner, so does anyone have any suggestions or help? Anything would be appreciated, I can’t ruin another pair of underwear 🙄🙄
