Menstrual Cup Size Guide
-
Before your period, your uterus relaxes and drops your cervix down lower into your vagina, the entrance to the cervix opens and the blood flows into the vagina - this may also vary from person to person.
Because of this you may find that your cervix is lower on days 1 - 3 of your period, requiring a smaller cup. Then on days 3+ you may need a larger cup as your uterus tightens again, lifting your cervix up and slowly back into its normal position - You may need two sizes of menstrual cups to work with your active cervix!
The most important factor in choosing the right cup is knowing your cervix height.Â
HERE is a detailed page on cervix height.If you want to be absolutely sure about your cup size you need to check the height of your cervix every morning during your entire period. Then you can work out which cup would be best in terms of height. But you still need to be sure about the cup width.
