At the beginning, many women are hesitant to choose a menstrual cup size. You need to know that the size of the cup does not depend on the amount of flow.
As you can see in the picture, women under 30 years old WITHOUT vaginal births should use cup size S
Older women with or without vaginal deliveries should use size L
Cup size does NOT depend on the amount of flow
Many times the mistake is made of assuming that the size of the menstrual cup depends on its capacity.
Remember that the vagina is flexible and has muscles. In general and if you have not had any health problems, your vaginal muscles should tuck the cup in perfectly when it is inserted into the vagina. However, there are several scenarios where the muscles have lost smoothness or simply the vaginal canal is wider.
