How will I know when to empty my menstrual cup?
How often to empty your menstrual cups depends on your cup size and your flow. When you first try a menstrual cup, you will realize pretty soon when to empty it.
The first day you wear it, check 3h later and that will give a good indication on how often you need empty it. The flow is usually different on each day of the cycle.
Personally, the first 2 days I put it in the morning, empty it around lunch time and then before bed. The remaining days, just morning and evenings are fine.
Everyone is different, get to know your body.
