If you’re interested in using a menstrual cup, talk with your gynecologist. Although you can buy any of the brands online or in most stores, you’ll first have to find out what size you need. Most menstrual cup brands sell small and large versions.
To figure out the right menstrual cup size for you, you and your doctor should consider:
- your age
- length of your cervix
- whether or not you have a heavy flow
- firmness and flexibility of the cup
- cup capacity
- strength of your pelvic floor muscles
- if you’ve given birth vaginally
Smaller menstrual cups are usually recommended for women younger than 30 years old who haven’t delivered vaginally. Larger sizes are often recommended for women who are over 30 years old, have given birth vaginally, or have a heavier period.
