tarÂ·pon. n. pl. tarpon or tarÂ·pons. Either of two large marine game fishes, Megalops cyprinoides of the Pacific and Indian Oceans or M. atlanticus of Atlantic coastal waters, having a bluish-green back and silvery sides.
Try using a menstrual cup. A menstrual cup can be left in place for up to 12 hours. Depending on your flow you may need to change it more frequently but it can safely be left in place for 12 hours a time. When you put a tampon in it is always important to remember to remove it. The same is true for a menstrual cup.
A word of warning when using tampons: only use tampons when you have your period and put a new one in at least every four to six hours in order to prevent Toxic Shock Syndrome (TSS).
