To fold a menstrual cup, flatten it and fold it in half into a C-shape. That C-fold is the one Lunette's instructions use and the easiest place to start. If it feels too wide going in, try the punch-down fold or the 7-fold: both make the tip you insert first smaller. Whichever fold you use, check afterwards that the cup has opened.
The 3 folds to try
| Fold | How | Good for |
|---|---|---|
| C-fold (U-fold) | Flatten the cup, then fold it in half so the rim forms a C | Starting out; opens easily |
| Punch-down fold | Push one point of the rim down into the base, then pinch the sides together | A smaller tip to insert |
| 7-fold | Flatten the cup, then fold one top corner down diagonally so it looks like a 7 | A smaller tip; a middle ground |
How to insert the folded cup
- Keep the cup folded and guide it rim-first into the vaginal canal.
- Aim toward your lower back, not straight up.
- Let go and let the cup open.
- Run a clean finger around it. It should feel round and firm.
The full walk-through is in how to use a menstrual cup.
What if the cup won't open?
A cup that stays folded or dented is a common reason for leaks. Try these, one at a time:
- Rotate it. Hold the base and turn the cup a full turn.
- Pull down gently and let go, so the rim can spring open lower down.
- Run a finger along the side to let a little air in under the rim.
- Change your fold. The C-fold opens more readily than tighter folds.
- Check the size. The menstrual cup size guide explains which Lunette size suits your body.

FAQ
Does it matter which fold I use?
Not for how well the cup works. Use the fold that goes in comfortably for you and opens reliably.
Can I practise before my period?
Yes. A dry run before your period is fine, and getting used to a cup can take several cycles. See the best menstrual cup for beginners.
If your cup clearly doesn't work for you after a fair try of two to three cycles, Lunette refunds it or sends you the other size. Choose your Lunette menstrual cup.
