Some women do find that the stem protrudes out the opening of their vagina. This can be due to the fact that their cervix sits low, or their vaginal length is short – and this is very common. The stem of your cup should not be outside your vagina as it can be uncomfortable and cause some irritation to your labia throughout the day. If the stem is too long, you can trim it until you find a comfortable fit. Cut a small amount at a time until it is the right size.
