Bleeding inserting tampons?

You should only be using tampons during menstruation or withdrawal bleeds - during full bleeding. Tampons absorb blood and vaginal moisture so result in the vaginal walls becoming ulcerated and split, with less blood the damage is more severe and this is not only uncomfortable but increases risk of TSS as damaged vaginal tissues gives TSST-1 toxins responsible for TSS a direct route into the bloodstream. If you're not menstruating and use tampons then the tampon can cause more vaginal tissue damage and result in bleeding.
