🌸 Understanding the different cup sizes
Menstrual cup capacity and menstrual cup size: how to choose without making a mistake? Choosing the right menstrual cup size ensures optimal comfort and prevents leaks. A washable cup or menstrual cup that fits your body, your anatomy, your vagina, and your menstrual flow lets you experience a stress-free period while being eco-friendly.
Before we go any further, know that Louloucup offers you two different cup models:
- the Louloucup Rose Classic,
- and the Louloucup Soft Turquoise.
Both of these types of internal, washable period protection come in two sizes: size S and size M.
To choose the right protection (a cup that suits your needs and expectations), it’s essential to know the available sizes and their features.
❋ Common cup sizes on the market and their features
At LouLoucup, our menstrual cup range comes in two distinct sizes:
- Small: Perfect for light flow, this size is especially suitable for young girls, virgins, or anyone with a light period.
- Medium (Medium Size): Perfect for medium to heavy flows, recommended for women who have given birth vaginally.
Some brands of internal reusable period products (cups, discs) offer a larger size for very heavy flow. The Louloucup medium model does the job perfectly for especially heavy periods. Its capacity is impressive!
❋ Cup size: for a deeper dive
To determine the ideal size and capacity of your cup, it’s important to consider several factors.
- The length of the vaginal canal. A cup that's too short might not cover the cervix properly, while one that's too long could be uncomfortable.
- The flexibility and shape of the period protection. LouLoucup offers a patented cup shape, designed to fit your anatomy without risk of irritation. This little ultra-soft inverted bell is gentle and unfolds easily once inserted.
- Previous experience. Are you already a user of menstrual discs or disposable tampons? Then you probably already have an idea of what size will work for you.
🌸 Assess and understand your menstrual flow
Before choosing your washable menstrual cup, it’s essential to really understand your flow.
❋ To help you determine your menstrual flow
-
How often do you change your usual period protection?
A woman or teen with a light flow can get by changing her period protection just once or twice a day. Someone with a heavy flow will feel more comfortable changing every two to three hours.
- How much blood do you lose per day, approximately? Take a few days to observe and note how much blood you lose. This will help you estimate whether your flow is light, medium, or heavy.
-
Is your flow steady or does it change during your period?
Some days may be heavier than others. Knowing these changes will help you pick a cup that fits every situation.
❋ Different types of menstrual flow
-
Light flow: just a few drops scattered throughout the day. Protection is usually changed rarely. ☞ A menstrual thong is ideal!
-
Medium flow: steady flow, requiring you to change your protection at regular intervals to stay comfortable. ☞ A classic period panty or a small menstrual cup are perfect.
- Heavy flow: A large amount of blood, requiring frequent changes of protection to avoid leaks, saturation, or discomfort. ☞ A menstrual cup or high-waisted period underwear with double protection are great options!
❋ Choosing your Loulou menstrual cup based on your menstrual flow
| Flow type | Cup size | Personalized Advice |
| Light flow | Small | Ideal for young girls, the teenagers and for first-time users. The small size offers an easy grip and a gentle insertion. |
| Medium flow | Medium | Suitable for most women who regularly use tampons. Offers an excellent balance between capacity and comfort. |
| Heavy flow | Medium with caution | For heavier flows, the medium size is designed to hold a substantial amount of blood. However, it’s important to pay attention to any signs of discomfort so you can adjust the positioning. Why not wear a period underwear to prevent any potential leaks? |
❋ Louloucup’s ultimate tips: one size / one flow
-
For a light flow.
Choose small or size S. Its design allows for easy and discreet insertion, perfect for those new to using a cup. This size provides enough protection without bulk, even on lighter days.
-
For medium flow.
The medium size or M size is the most recommended. It offers enough capacity to collect blood while staying comfortable. If you’re active, athletic, or love to swim or run, this cup size is for you!
-
For a heavy flow.
Even though LouLoucup mainly offers two sizes, the medium size was designed to handle heavier flows thanks to its large internal reservoir. Be sure to empty/rinse your cup regularly (every 4 to 6 hours) to avoid any risk of leaks or discomfort.
🌸 Other factors to consider when choosing your menstrual cup
Besides flow, several other factors can influence your choice of menstrual cup size and capacity.
❋ Pregnancy history
After pregnancy, the pelvic floor can lose its tone. The perineum becomes less firm. The vagina may feel stretched. A woman who has already given birth might prefer a firmer model with slightly more capacity to ensure a good seal.
❋ Age
If you’re new to using menstrual cups, it’s often recommended to start with the small size to get used to the insertion technique, then consider switching sizes if needed.
❋ Personal preferences
Some women prefer a slightly higher capacity for extra security. In this case, it might be wise to choose the medium size, even for light to medium flow, to benefit from added protection.
❋ Daily activities
For athletes or anyone with an active lifestyle, the LouLoucup menstrual cup offers great freedom of movement. Make sure to choose a size that doesn’t bother you during activities, whether it’s swimming, sports, or a busy day.

❋ Sterilizing your cup: a step you shouldn’t skip
Before each use (at the start of every new period), wash your hands and sterilize your cup! You can use a dedicated sterilizer (available on our e-shop) or simply boil it in water for about 5 minutes. This step is crucial for maintaining top hygiene and preventing bacteria and odors.
❋ Insertion and positioning
Proper insertion of your menstrual cup is essential for it to collect blood effectively. Here are a few tips to help you (you’ll find all our detailed advice in the instructions included with your cup):
- Breathe and relax! Take a few deep breaths to release tension. It’s important so your muscles aren’t too tight when you insert it.
- Insert the cup while sitting or squatting. There are several possible positions—try a few. These positions make insertion and proper placement easier.
- Once inserted, the cup unfolds and should rest against the walls of your vagina. The cup needs to be inserted until its rim opens up to create a seal against the vaginal wall.
❋ Regular and thorough cleaning of your cup
During the day, it’s recommended to empty and rinse your cup every 4 to 6 hours to avoid discomfort or leaks. Regular cleaning also helps extend the life of your cup and ensures a pleasant experience. When you go to the bathroom, take the opportunity to empty your cup and rinse it with clean water. You can then reinsert it.
❋ Do not sleep with a cup
Although the menstrual cup is a very reliable period product, it’s recommended not to wear it overnight to reduce any risk of toxic shock syndrome. For overnight hygienic protection, we highly recommend using an ultra-soft, comfy organic cotton period underwear for heavy flow. You’ll sleep soundly, we promise!

🌸 Menstrual cup capacity FAQ
❋ Can I use a cup if I have an IUD?
Yes, it is absolutely possible to use a menstrual cup if you have an IUD (intrauterine device). However, it’s important to check with your healthcare provider (doctor, gynecologist, or midwife) to make sure there are no interactions or contraindications.
❋ How do I know if my cup is inserted correctly?
A properly inserted cup shouldn’t be felt at all—it should be comfortable and invisible. You shouldn’t feel any discomfort or pain.
❋ What should I do if my cup leaks?
If you notice leaks, first check that the cup is properly inserted and has formed a good seal against the vaginal wall. Empty and reposition it. If you’re still unsure, contact LouLoucup customer service—they’ll be happy to help you find the best solution for your situation.
❋ How do I care for my cup?
To ensure optimal hygiene, it’s recommended to wash your menstrual cup with clear water or mild soap before and after each use. Regular sterilization is also essential: you can use a dedicated sterilizer or boil it in a pot of water for 5 minutes. Always make sure your cup is completely dry before storing it.
