You're standing in your bathroom, holding a small silicone bell, and wondering how on earth that thing is supposed to fit comfortably inside you. It looks huge. Honestly, the first time I looked at one, I thought it was a prank. But once you figure out how to put in a diva cup, your entire period experience changes. No more soggy strings. No more emergency runs to the pharmacy for tampons. Just twelve hours of freedom.
Most people struggle because they treat it like a tampon. It isn't. It’s a completely different mechanical process. A tampon absorbs; a cup collects. A tampon goes high; a cup sits low. If you try to jam it up toward your cervix like a Rayon plug, you're going to leak, and it’s going to hurt.
Let's get into the weeds of how this actually works.
The Prep Work Nobody Mentions
Wash your hands. Seriously. You’re reaching into a very delicate ecosystem, and the last thing you want to introduce is bacteria from your phone or a doorknob. Use a mild, unscented soap. Anything with heavy perfumes or oils can degrade the medical-grade silicone of the cup or, worse, cause a yeast infection.

Check the air holes. Look at the rim of your Diva Cup. See those tiny pinpricks? Those are vital for the suction seal. If they’re clogged with residue from your last cycle, the cup won't open properly. Use a toothpick or just fill the cup with water, palm it, and squeeze so the water squirts out the holes.
Relax your jaw. It sounds weird, but your pelvic floor is physically linked to your jaw tension. If you’re gritting your teeth because you’re nervous, those vaginal muscles are going to clamp shut like a vault. Take a breath. Drop your shoulders.
The Fold: Finding Your Style
You can't just shove the cup in as-is. You have to fold it to reduce the diameter. Most instruction manuals show the "C-Fold," where you flatten the cup and fold it in half so the rim looks like a letter C.
It’s the most famous fold. It’s also, frankly, the hardest to insert because the widest part of the fold enters all at once.
Try the Punch Down fold instead. Take one finger and push the rim of the cup down into the base. Squeeze the sides together. This creates a much narrower, pointed tip. It’s roughly the size of a tampon, making the initial entry way less intimidating. Another solid option is the 7-fold, where you fold one corner down toward the stem, creating a shape that looks like the number seven. This one is great because it has a smaller release point, meaning it won't "snap" open too aggressively, which can be a bit startling if you're sensitive.
How to Put in a Diva Cup Step-by-Step
Positioning is everything. Some people find it easiest to squat in the shower. Others prefer propping one leg up on the toilet seat. If you’re a beginner, the "deep squat" is usually the winner because it shortens the vaginal canal and opens everything up.
- Get it wet. Use water or a water-based lubricant. Avoid oil-based lubes at all costs; they will ruin the silicone. A little moisture on the rim makes a massive difference.
- Angle it toward your tailbone. This is the mistake most people make. They try to push the cup straight up toward their head. Your vaginal canal actually angles back toward your spine. Aim the cup toward the small of your back.
- The Insertion. Hold your chosen fold firmly. Slide it in. Keep it folded until the entire rim is inside. If you let go too early, it’ll pop open at the entrance, which is uncomfortable.
- The Pop. Once it’s in, let go. You might hear or feel a literal pop. That’s the suction forming.
- The Rotation. This is the secret sauce. Reach in and grab the base of the cup (not the stem, the actual ribbed bottom of the cup). Give it a full 360-degree turn. If it rotates easily, it’s open. If it feels stuck or dented, it hasn't sealed yet.
Why You Might Be Leaking
If you’ve followed every step and you’re still seeing spots on your underwear, don't panic. It happens. Usually, it’s because the cup is sitting next to your cervix rather than under it.
Your cervix is like a small, firm donut (it feels like the tip of your nose). During your period, it can move lower or tilt to one side. If you slide the cup past it, the blood will just bypass the cup entirely. Use a clean finger to feel around the rim once it’s inserted. You should feel the smooth silicone all the way around. If you feel a squishy bit of tissue outside the cup, that’s your cervix, and you need to re-adjust.
Trimming the Stem
The Diva Cup has a long, tapered stem. For some people, this is great for reach. For others, it pokes the vaginal opening and feels like a constant itch or a pinch.
You can trim it.
Take the cup out first—don’t try to do this while it’s inside you. Use a pair of clean nail scissors. Cut a little bit at a time. Some people end up removing the stem entirely. As long as you can still reach the base of the cup to break the seal, you don't actually need the stem.
Removal: Don't Just Pull
Removing the cup is just as important as putting it in. Whatever you do, do not pull on the stem like it’s a tampon string. The Diva Cup stays in place via a vacuum seal. If you pull without breaking that seal, you’re basically trying to give your internal organs a hickey. It hurts, and it's ineffective. Instead, use your muscles to "push" down—like you’re having a bowel movement. This brings the cup lower. Use your thumb and forefinger to pinch the base of the cup. This breaks the suction.
Once the seal is broken, wiggle it side to side as you pull it out. Keep it upright so you don't spill the contents. It’s a bit of a learning curve, and honestly, you might get some blood on your fingers the first few times. It's fine. It's just blood.
Maintenance and Longevity
The Diva Cup is an investment. It’s made of high-quality medical silicone, which means it can last for years if you treat it right.
During your cycle, rinsing it with warm water is enough. Once your period is over, you need to deep clean it. Boil a pot of water, drop the cup in, and let it sit for 5 to 7 minutes. Don't let it touch the bottom of the pot, or it might melt—some people put the cup inside a whisk to keep it floating.
Avoid harsh cleaners. No bleach. No vinegar. No dish soap. If the cup starts to smell or develops a yellowish film, it’s usually due to a buildup of protein. You can soak it in a 3% hydrogen peroxide solution for a few hours to restore the color, but don't do this too often as it can weaken the material over time.
Troubleshooting Common Issues
"I can't get it out." First, breathe. The cup cannot get lost inside you. Your cervix acts as a literal dead-end. If the cup has moved up high, it’s usually because you’re tensed up. Sit on the toilet, relax, and try again in ten minutes. Gravity is your friend here.
"It's pressing on my bladder." If you feel like you suddenly have to pee the moment the cup is in, it might be too firm for you or positioned too high. Try sliding it a bit lower. The Diva Cup is designed to sit lower than a tampon, just above the pubic bone. If it’s still pressing, you might need a different size or a softer brand of cup.
"The stem is irritating me." As mentioned before, trim it. But also check the angle. If the cup is tilted, the stem might be rubbing against the labia. Ensure the cup is centered and the stem is tucked comfortably inside.
Actionable Next Steps for Success
To master the Diva Cup, don't wait until the first heavy day of your period to try it out. That's a recipe for a bathroom floor disaster.
- Practice during your "dry" days. Use a little water-based lube and try inserting and removing it when you aren't under the pressure of an active bleed.
- Wear a backup. For the first two cycles, wear a thin liner or period underwear. It takes time for your muscle memory to learn how to create that perfect seal every single time.
- Map your anatomy. Use a clean finger to find your cervix. Knowing if it sits high, low, or tilted to the left will tell you exactly where the cup needs to go.
- Invest in a dedicated wash. While water is fine, using a pH-balanced cleanser specifically made for silicone cups can help prevent irritation if you have sensitive skin.
Switching to a menstrual cup has a steep learning curve, usually taking about three cycles to feel like a pro. Once you hit that point, you'll likely never want to go back to disposables. The key is patience and a willingness to get a little messy while you learn the ropes.
