Check out our questionnaire:

Am I under 35 and have had no full-term pregnancies?

YES: You're likely a small size.

NO: You're likely a large size.

Have I given birth through the vagina (age does not matter)?

YES: You're likely a large size.

NO: You're likely a small size.

Am I very physically active or do exercises that tone my pelvic floor? Or, Did I go through pelvic floor therapy?

YES: You may still fall into the large cup size category but could potentially fit a size small as well. If you're undecided, consider sizing up.

Do you know the height of your cervix?

NO IDEA: Check our blog titled My Cervix Height
LOW: Small Size
HIGH: Large Size

I just turned 35 years old, do I need to switch to a larger menstrual cup?

NO: If the cup you used during your 34th year still fits well, continue using it. If you experience slipping, a larger diameter may help, but otherwise, stick with what's working until it's time for a replacement.

If your answers lead you to the large size but you're still facing leakage issues, consider shortening the hours of wear. For instance, if you typically wear it for 5-8 hours, try reducing it to 3-4 hours.

Keep in mind, this is a recommendation - every body is unique! If you find yourself needing two menstrual cups, explore our product options, and enjoy discounts when you purchase the Two Menstrual Cups in 1 Box. We hope this questionnaire makes your decision-making process a breeze!
