l do not wanna have my period while at the beach l dont want string to hang out!! but l have to where a tampon...what do l do

Unless you're swimming naked, no one should see the string of your tampon.
If it hangs too low, tuck it in between your vaginal lips.

As long as you're not swimming naked no one is going to see the string. You could skip your period though if you're already taking birth control. Just start a new pack instead of taking the placebo pills.

Shove a tampon up in that tight joint!
