It’s hard to tell if your period will stop once you are in the water. If it is at the end of your cycle or your period tends to be light, it may stop completely but there is no guarantee. If you want to swim and not feel self-conscious about the possibility of bleeding, why not consider wearing a tampon? Using a small slender tampon may be easier than you think. Ask your mom for suggestions and watch our tampon video. Tampons are especially made to absorb menstrual flow while swimming.
