surprisedI was clicking around on the Lunette.com website and under FAQ's is the question: How do I know if I have heavy or light periods?
The limit of heavy periods in considered to be 80 milliliters of flow.
The Mansfield-Voda-Jorgensen Menstrual Bleeding Scale can give you indication about how much you are bleeding:
1. Spotting. A drop or two of blood, not even requiring sanitary protection though you may prefer to use some.
2. Very light bleeding. You would need to change the least absorbent tampon or pad one or two times per day, though you may prefer to change more frequently.
3. Light bleeding. You would need to change a low or regular absorbency tampon or pad two or three times per day, though you may prefer to change more frequently.
4. Moderate bleeding. You would need to change a regular absorbency tampon or pad every three to four hours, though you may prefer to change more frequently.
5. Heavy bleeding. You would need to change a high absorbency tampon or pad every three to four hours, though you may prefer to change more frequently.
6. Very heavy bleeding or gushing. Protection hardly works at all; you would need to change the highest absorbency tampon or pad every hour or two.

If you're bleeding moderately or more, the bigger size Lunette cup might be better for you.
I never knew this info existed and i'm shocked i fall under the 'very heavy bleeding' category...i thought i would be under 'heavy bleeding' since i've read of others around here that lose lots more than me! Wow.
