Each person has a different cervix height ranging from low, mid, or high. Cervix position can also change during your cycle. It’s important to know your cervix height to ensure the cup your purchase won’t be too long and fall out, or too short and be difficult to reach.

While there are several differences between menstrual cups and discs, here are the 3 main ones:

1. A menstrual disc stays in place using suction around the vaginal wall, whereas a disc stays in place by lodging behind the pubic bone.
2. A menstrual disc is messier to remove than a menstrual cup.
3. A menstrual disc can be worn during sex, whereas a menstrual cup cannot.

Both menstrual cups and discs can be worn for up to (but not longer than) 12hrs. However, if you have a very heavy flow, you may need to empty your cup or disc every 3-4hrs on your heaviest days. Knowing your level of flow will help you work out how often you may need to empty your cup or disc.
