I wear period underwear instead of a pad for backup. Well, I used to when I worked from home. Now that I’m back in the office I’m back to tampons and pads.
Sometimes with my disc, it is totally right, no leaks even on heavy days. Other times, it leaks when I cough or sneeze. SUper random and no predicting when it will be right and when it slip out of place. But still better and cheap then tampons! I always wear a panty liner with it.
