How to Use a Low Cervix Menstrual Cup Kit Correctly

Quick answer

A low cervix cup works best when the whole cup sits low and shallow, with the stem trimmed or tucked just inside the vaginal opening rather than pushed high like a standard cup. Insert it angled toward your tailbone, then check that the rim is fully open and the base sits no deeper than your fingertip can comfortably reach. If it keeps riding up or leaking, the cup is usually too long or too firm for your anatomy, not inserted wrong.

Find your cervix height before you insert anything

Wash your hands and insert one finger until you feel your cervix, which feels like the tip of your nose. Note how deep your finger is when you reach it. A low cervix typically sits within the first knuckle or two, roughly 1 to 2 inches inside. Do this on the heaviest day of your period, because the cervix drops lower then. That measurement tells you whether a short cup will sit comfortably or whether a standard-length cup will press against your cervix and leak.

• Measure on your heaviest flow day, not mid-cycle.
• If your fingertip barely reaches, you need a short cup.
• Recheck after your first cycle; height can shift.

Choose the right short cup and handle style

Low cervix cups are shorter in the body, but the handle still matters. A stem handle gives you something to grip during removal, while a ball or ring handle can be easier to find with your fingertips if the stem tends to poke. The MeLuna Low Cervix Menstrual Cup Kit pairs a Shorty cup with a foldable microwave sanitizer, and you choose the handle style, size, and color when ordering. Pick the smallest size that holds your flow for 4 to 6 hours; a cup that is too large will sit lower and feel more noticeable.

• Shorty body length is the key feature for a low cervix.
• Handle style is about removal grip, not capacity.
• Size up only if you are changing the cup more than every 4 hours.

Fold and insert at a shallow angle

Use a punch-down or C-fold and aim the cup toward your tailbone, not straight up. Because a low cervix cup sits shallow, you only need to push until the rim clears your pelvic bone, usually about one finger deep. Stop there. Pushing it higher defeats the purpose and can make the stem press against your cervix, which causes cramping and leaks.

• Angle back, not up.
• Insert only until the rim is past the pubic bone.
• If you feel pressure, pull back slightly.

Check the seal and placement

Run a finger around the rim to confirm it is fully open and not dented. Then press gently on the side wall of the cup to create suction against the vaginal wall. The base should sit low enough that you can reach it easily with one finger. If the cup feels like it is sitting on your cervix rather than around it, break the seal, remove it, and reinsert at a shallower depth.

• A dented rim will leak.
• The cup should surround the cervix, not press on it.
• You should be able to touch the base without straining.

Remove, clean, and sanitize without boiling

Pinch the base to break the seal, then rock the cup gently side to side as you pull. Do not pull by the stem alone, because that can cause suction pain. Rinse with water during your cycle, and sanitize between cycles. The MeLuna Menstrual Cup Sanitizing Kit uses a reusable container and Milton Mini Tablets for cold-water sanitizing, which is useful if you do not want to boil a pot or rely on a microwave.

• Always break the seal before pulling.
• Rinse with plain water between changes.
• Sanitize at the end of your cycle, not every change.

Step-by-step: using your low cervix cup kit

1. Measure cervix height on your heaviest day: Wash your hands and insert one finger until you feel your cervix. Note the depth. If it is within the first knuckle or two, you have a low cervix and need a short cup. Checkpoint: if you cannot reach your cervix with one finger, a standard cup may fit better.
2. Pick your Shorty size and handle style: Choose the smallest size that holds your flow for 4 to 6 hours. A stem handle is easiest to grip; a ball or ring handle can be easier to locate if the stem pokes. Mistake to avoid: sizing up for capacity when your cervix is low, which makes the cup sit too deep.
3. Fold and insert at a shallow angle: Use a punch-down or C-fold and aim toward your tailbone. Push only until the rim clears your pubic bone, about one finger deep. Checkpoint: if you feel pressure or cramping, the cup is too deep. Pull back slightly.
4. Check the seal and rim: Run a finger around the rim to make sure it is fully open. Press the side wall to create suction. The base should sit low enough to touch easily. Mistake to avoid: leaving a dent in the rim, which causes leaks.
5. Remove by pinching the base: Pinch the base to break the seal, then rock side to side while pulling. Do not pull by the stem alone. Checkpoint: if removal hurts, stop and break the seal more completely before pulling.
6. Sanitize between cycles: Rinse with water during your cycle. At the end, use the microwave sanitizer from the kit or the cold-water Milton Mini Tablets if you prefer no boiling. Next step: sanitize once at the end of your period, then store the cup dry and uncovered.
