A menstrual cup is form of reusable menstrual protection. It is inserted into the vagina to collect menstrual fluids. Once in place it forms a seal, preventing blood flowing out of the vagina by collecting it in its “cup” shaped reservoir. Unlike a tampon which absorbs the blood along with the vagina’s natural secretions, a menstrual cup simply holds the fluids until you remove it – so they do not dry out the vagina and do not hold the TSS risk that tampons do.
They hold around 20-30ml, which is for most women will cope with a full day without emptying, and at most perhaps you would need to empty it a few times a day for a very heavy flow. A menstrual cup will last (with proper care) for around 10 years, perhaps longer, so while the initial outlay is high, it pays for itself with savings pretty quick.
