Menstrual cups are a new type of period product that you use like tampons to collect menses during the period. 
Unlike a tampon which absorbs the blood along with the vagina’s natural secretions, a menstrual cup simply holds the fluids until you remove it – so they do not dry out the vagina and do not hold the TSS risk that tampons do. They hold around 20-30ml, which is for most women will cope with a full day without emptying, and at most perhaps you would need to empty it a few times a day for a very heavy flow.

How to use a Monzcare menstrual cup?

Steps 1: Read the instructions accompanying your choice of menstrual cup.

Read over the pamphlets that come with your cup until you feel comfortable to go ahead. Also, see the wikiHow on cleaning a menstrual cup for directions on keeping it clean, and if you're on the fence about using a cup, read how to decide whether to use a menstrual cup to help you make up your mind. And if you don't have a menstrual cup already, read wikiHow's advice on buying a menstrual cup for directions on picking out the right cup for you.

Steps 2: Try inserting the menstrual cup the first time in the privacy of your own bathroom. 

Most users do not get the hang of it until after a couple of tries, so this will be far better than using a public bathroom. Also, although you may be tempted to do a dry run while you're not on your period, you really shouldn't because it's generally more lubricated and your cervix may be in a different position while you're menstruating. So for the first time, make sure it is during your period as well.

Steps 3: Practice different folds of the menstrual cup.

The C fold shown on instruction manuals isn't the best technique for many women. When you use the C fold, the widest part of the cup is just at the beginning. Another fold (there are many to choose from) is the punch-down fold. To make this fold, place your finger on the rim of the cup, and push it down into the cup. See the video below for more folds you can try.

Steps 4: Wash your hands with soap and rinse the cup with water to remove any dust or dirt from your hands and the cup.

The first time you use it, it should be boiled as well. Soap should never be used on a menstrual cup. It can cause yeast infections amongst other problems.

Steps 5: Stay relaxed and try not to tense your pelvic muscles.

This may make it painful or difficult to insert the cup. Your pelvic muscles are the ones you use to stop and start peeing. Practice loosening and tightening these muscles (aka doing kegel exercises) so you will be able to relax them during insertion. Be patient; the first time inserting it is always the hardest, so don't give up if you're having trouble at first-- but do take a break if you become overly frustrated.

Steps 6: Get into a comfortable position. 

You might like to try inserting the cup while over the toilet. You can also try squatting down in the tub or shower; standing and putting one leg on the edge of the toilet or tub; putting your back against a wall and getting into a squat position; or lying down on the floor with your knees up and legs apart.

Steps 7: Find your cervix. 

Stick a finger inside your vagina and feel for your cervix, which feels kind of like the tip of your nose. It is a small, squishy nub with an indentation in the middle. Aiming the cup in the direction of your cervix will help. This way you won't accidentally poke your cervix with the cup, or take up space in the cup with your cervix. If you can't find your cervix, this probably means it's very high, and in that case, your cervix probably won't cause any problems.

Steps 8: Insert the menstrual cup. 

Fold the cup and then hold it with one hand (stem facing downwards). Spread apart your labia and find the opening of your vagina with your other hand. Now push the cup in at an about a 45-degree angle towards your pubic bone, not straight up. The cup should pop open. Continue to push the cup in until it is comfortable. (The cup may ride low or high depending on your body, but the base of the cup [although not necessarily the stem] should not clear your vaginal opening.)

Steps 9: Make sure that the menstrual cup is fully open.

You may have heard or felt a "pop." This is a sign that the cup has opened. Otherwise, reach up and feel around the base of the cup. It should be round or at least oval. (The cup may not ever open up all the way, depending on your body shape.) If it's not open, you can open it manually with a hand. Also try doing a few Kegel exercises, squats, jumping jacks, or rotating the cup in a full circle by twirling the base. You can also reach up with a finger and press part of the vaginal wall out of the way, so that air can travel up and fill the cup. You may feel more comfortable with the cup closer to your cervix than pictured in the instructions. 

Steps 10: Wait up to twelve hours. 

If you have a heavy flow, you will have to empty it more often, because this is the maximum recommended time. For your first cycle with a cup, you'll have to do a bit of experimenting to find out how long you can leave your cup in before leaking. (It's a good idea to wear a backup pantyliner; cloth pantyliners are a good reusable option.)

Steps 11: Remove the cup. Bear down with your muscles so the cup will travel down farther. 

Continue doing this until you can reach the stem. Wiggle the cup back and forth and down. Get a better grip on the actual base, not just the stem, of the cup and continue to pull it out. Pinching the base helps to break the vacuum and makes it easier to remove the cup. When you get to the opening of your vagina make sure you take it out upright to reduce spillage. If the rim of the cup is too wide to remove comfortably, use a finger to fold the cup into a C fold or a punch-down fold before you take it out of your vagina. If you're removing the cup over a toilet, you can let the contents spill out the "back" as you remove the cup.

Steps 12: Dump the contents of the cup in the toilet or sink.

Rinse the cup with water. To clear the suction holes of menstrual fluid, bend the cup at the suction holes under the water. You can also fill the cup with water, cover the opening with your palm, and then squeeze the cup to squirt water out the holes-- keep clear! Dry your cup if it's too slippery (although the water and slipperiness may help you out) and reinsert.

Steps 13: Learn how to clean the cup. You can boil the cup.

Use sterilizing tablets, swab it down with rubbing alcohol, or choose from other methods. See wikiHow's instructions on how to clean a menstrual cup for directions and choose the method that works best for you.

Steps 14: Remember that it may take a while to get used to using a menstrual cup.

Take your time. Menstrual cups have a learning curve of about three to four cycles and if eventually, you find out it's not for you, that's fine. If you still want to use a reusable menstrual product, you can try cloth pads or sea sponges.
