Which size is better for a menstrual cup?
Choosing the right menstrual cup size depends on several personal factors. Here’s a quick rundown to help you decide:
1. Age
-
Under 30 years old: Small or Medium size is usually better.
-
Over 30 years old: Medium or Large size is often recommended.
2. Childbirth History
-
No vaginal births: Small or Medium size tends to fit best.
-
Vaginal births: Medium or Large size is typically better to accommodate changes in anatomy.
3. Flow Level
-
Light to medium flow: Small or Medium cup works well.
-
Heavy flow: Medium or Large cup with higher capacity is ideal.
4. Cervix Height
-
Low cervix: Shorter cups or those with a trimmed stem are more comfortable.
-
High cervix: Longer cups are easier to reach and remove.
5. Pelvic Floor Strength & Activity
-
Strong pelvic muscles or active lifestyle: A firmer cup may be better to prevent leaks.
-
Sensitive or relaxed muscles: Softer cups offer more comfort.
General Recommendation
-
If you’re new and unsure: Start with a medium size — it suits many people well.
