The amount flow and your anatomy affects what size Lunette Cup you should choose!
Lighter flow? Model 1 might be for you.
Heavier flow? Give model 2 a go!
For teens and young users, the smaller model 1 makes for easier ins and outs.
For our Mums out there, you can use both sizes. Pregnancy changes a few things down there, so firstly take into account your new cervix position (if it's low use a model 1), and secondly your new flow volume post-birth.
If you have a low-sitting cervix, try the shorter model 1 for a better fit.
If you're a fitness goddess with strong vaginal muscles, consider using Model 1.
Sensitive bladder? The softer model 1 might be a match made in heaven for you.
