Choosing which size is best for you will depend on your flow, which is why having a different size cup for lighter and heavier days can work a treat! It also depends on your cervix height and anatomy, if you’re starting out the A Cup is a great place to start. If you have a heavier flow you can just empty more regularly.
A Cup: 42ml, Light to Medium Flow
B Cup: 68ml, Medium to Heavy Flow
