What menstrual cup size is right for me?
There are so many things in life you have to consider, and your vagina's size has certainly not been one of them… until now. Not to worry! We have put together a complete menstrual cup size guide to empower you in choosing the correct menstrual cup size for you.
FloAngel menstrual cups are soft and pliable — our period cups conform to your body shape. We are all made differently, and choosing the correct cup size will ensure a more comfortable fit. If you choose the correct cup size, you should not be able to detect your cup when inserted (amazing, right!).
When it comes to choosing the correct menstrual cup size that will suit you, there are two main factors to consider:
Have you given birth vaginally?
Are you over or under the age of 30?
These two factors are important because, as we age, our pelvic floor becomes weaker — and giving vaginal birth also impacts our pelvic floor. With these factors in mind, we recommend the following:
- Large If you have given a vaginal birth
- Small If you have given birth with a C-section and are under the age of 30
- Small If you are under 30 and have never given birth
- Large If you are over the age of 30
There are times when you would have to consider other variables when selecting the correct menstrual cup size for you. These include the following.
Are you a virgin or teenager?
Menstrual cups can be worn at any age once menstruation starts. We do recommend that users are comfortable with their body before using a menstrual cup.
Using a menstrual cup can potentially stretch or cause changes to the hymen, but it's important to understand that the hymen is a flexible and stretchable piece of tissue that naturally changes over time due to various activities and hormonal changes. The hymen is not a solid barrier that "breaks" during activities like using menstrual products, sexual intercourse, or physical activities.
Here's some information to consider:
- Flexibility:
The hymen is a thin membrane located at the opening of the vagina. It has an opening that allows menstrual blood to pass through. Using a menstrual cup, which is designed to be inserted into the vagina, may stretch the hymen slightly, similar to how inserting a tampon or engaging in physical activities can. However, this stretching is usually minimal and not necessarily indicative of loss of virginity or any harm.
- Normal Activities:
Everyday activities like walking, running, riding a bike, or even using your fingers to explore your own body can also stretch or change the hymen. Many girls and women have hymens that naturally have an opening or are more flexible.
- Comfort and Relaxation:
Proper insertion of a menstrual cup involves relaxation and ensuring that the cup is inserted correctly. The vaginal muscles can stretch and accommodate the cup comfortably. It's important to use a cup that is the right size for you and to follow the recommended insertion and removal instructions to minimize any potential discomfort.
- Virginity Myth:
The concept of "virginity" is complex and varies culturally. It's important to remember that the state of the hymen does not determine someone's virginity. Virginity is a social and cultural construct and has different meanings in different societies.
If you have concerns about using a menstrual cup and its potential impact on your hymen, you can consider speaking with a healthcare provider. They can provide you with accurate information, address any concerns you may have, and offer guidance on using menstrual products comfortably and safely. Remember that the hymen is a normal part of female anatomy that naturally changes over time, and using menstrual products should not cause significant or harmful changes.
Pelvic floor tone and strength
Menstrual cup size selection may be different due to pelvic floor strength and tone. Pelvic floor strength is influenced by a combination of factors, including genetics, lifestyle, hormonal changes, pregnancy and childbirth, age, and certain medical conditions.
The pelvic floor is a group of muscles and tissues that provide support to the pelvic organs (such as the bladder, uterus, and rectum) and play a crucial role in various bodily functions. Here are some factors that can influence pelvic floor strength.
If you regularly do pelvic floor exercises, lead an active lifestyle, or do other exercises like yoga or pilates, we recommend the size Small — whether you have given birth vaginally or not.
There might be various reasons for a woman to have a weaker pelvic floor:
- A sedentary lifestyle
- Hormonal fluctuations and changes with age
- Chronic constipation
- Obesity
- High-impact activities that strain the pelvic muscles
- Medical conditions such as prolapse, neurological conditions and surgical procedures
In the case of weaker pelvic floor muscles, we recommend the suitable menstrual cup size will be the Flo Angel Large Menstrual Cup.
Cervical height
Cervix height refers to the position of the cervix within the vaginal canal. The cervix is the lower part of the uterus that connects to the vagina. It can move up and down throughout your menstrual cycle and can affect your comfort and the fit of a menstrual cup.
Understanding your cervix height can help you select a menstrual cup size that fits well and is comfortable to wear. There are generally three categories of cervix height:
Low cervix
- If you can easily reach your cervix with your finger, you likely have a low cervix.
- A low cervix means your cervix is closer to the vaginal opening.
- You may find a shorter or "low cervix" cup more comfortable, as it won't extend too far into your vaginal canal.
Medium cervix
- If you can reach your cervix with your finger inserted about to your second knuckle, you likely have a medium cervix.
- A medium cervix is located in the middle of the vaginal canal.
- Most standard or regular-sized menstrual cups should work well for individuals with a medium cervix.
High cervix
- If you can't easily reach your cervix or need to insert your finger deeply to reach it, you likely have a high cervix.
- A high cervix means your cervix is located deeper within the vaginal canal.
- You may prefer a longer cup that can accommodate your high cervix and provide a comfortable fit.
Selecting the right menstrual cup size based on cervix height is important because a cup that is too long for your cervix height might be uncomfortable or difficult to insert, while a cup that is too short might not provide adequate leakage protection.
To determine your cervix height, follow these steps:
- Wash your hands thoroughly.
- Insert a clean finger into your vagina until you feel your cervix. Note how far you can insert your finger before touching your cervix.
- Based on your findings, you can choose a menstrual cup length that corresponds to your cervix height.
When selecting a menstrual cup size based on cervix height, consider looking for cups labelled as "low cervix" or "short" if you have a low cervix, and opt for standard or regular-sized cups if you have a medium cervix. If you have a high cervix, you might consider cups with longer lengths for a comfortable fit.
Keep in mind that individual anatomy varies, and some experimentation might be necessary to find the best fit and comfort for you.
If you have a short vaginal canal (low cervix), please choose a small menstrual cup size. Flo Angel Lulu Menstrual Cups have a trimmable stem — in the event that your cervix is very low and you find the stem uncomfortable, you can simply cut the stem shorter. For a long vaginal canal (high cervix), we recommend a large cup.
It's important to note that pelvic floor strength and health can be improved through targeted exercises known as Kegel exercises. These involve contracting and relaxing the pelvic floor muscles to enhance strength and control. If you have concerns about your pelvic floor health, are experiencing symptoms such as urinary incontinence or pelvic pain, or are preparing for pregnancy or childbirth, it's a good idea to consult with a healthcare provider or a pelvic floor physical therapist for personalised guidance and exercises.
Period flow rate and flow volume
Period flow rate and volume are two distinct but related aspects of menstrual bleeding. Understanding both can help you choose the right menstrual cup size for you.
Period flow rate
Flow rate refers to how quickly or slowly menstrual blood is expelled from the body. It is usually categorised into different levels:
| Flow rate | Blood loss | Change product roughly every… |
|---|---|---|
| Light | Minimal blood loss | 6–8 hours |
| Moderate | Steady blood loss | 4–6 hours |
| Heavy | Significant blood loss | 2–4 hours |
| Very heavy | Exceptionally heavy blood loss | 1–2 hours |
Period flow volume
Flow volume refers to the amount of menstrual blood expelled over a specific period, usually measured in millilitres (ml) or the number of sanitary products used:
| Flow volume | Typical sanitary products per day |
|---|---|
| Light | Fewer than three small-sized products |
| Moderate | Three to five regular-sized products |
| Heavy | More than five regular-sized products, or a mix of regular and overnight |
| Very heavy | Frequent changes and high-absorbency products |
Menstrual cup usage and flow
When using a menstrual cup, understanding both flow rate and volume is essential when selecting the correct size:
- Choosing the right size: Understanding your flow rate and volume helps you choose a cup with the appropriate capacity and comfort level.
- Emptying frequency: Knowing your flow rate and volume helps you estimate how often you need to empty the cup to prevent leakage and discomfort.
- Monitoring and comfort: Monitoring the cup's fill level helps prevent overflow. Flo Angel menstrual cups have measurement lines to aid in gauging your flow volume.
Both flow rate and volume can vary from person to person and cycle to cycle. Tracking your flow patterns over several menstrual cycles can provide insights into your needs and will help you select the right menstrual products for each day of your period.
If your monthly flow is very heavy, the large menstrual cup size would be more suitable — although the small can also work and would just need to be emptied more often. For a light to normal flow, the small menstrual cup size would be perfect. Those with a heavy menstrual flow might consider buying two sizes — both the large and the small. The large would be worn on the first 2 to 3 days of your period, then switch over to the small for the remainder.
Flo Angel menstrual cups can hold the equivalent of 3 to 4 tampons, giving you up to 12 hours of continuous wear before you have to empty and reinsert. No matter what menstrual cup size you choose, you'll have a lot more freedom using a period cup than any other alternative period-care product.
