Why Your Menstrual Products Stop Working After Childbirth

Many women expect their bodies to change after childbirth, but few are prepared for how much these changes can affect everyday life. As an OB-GYN, I often hear concerns that women don't talk about out loud, don't discuss with friends, and sometimes don't even share with their partners. These are quiet, personal experiences, but they have a real impact on comfort, confidence, and quality of life.

After childbirth, many women start to notice that something has changed. Sometimes it affects their cycle, but more often it's how their body responds to it. Menstrual products that used to work perfectly suddenly stop working: a menstrual cup may start to cause pressure or leak, tampons can become painful or difficult to insert, pads may begin to irritate the skin or create a constant feeling of moisture, and a menstrual disc that used to stay in place may start to shift. For many women, this is unexpected and frustrating.

It's important to understand one key point: in most cases, the problem is not the product and it's not the woman. The body has changed, and with that, the way menstrual products sit and function also changes.

What actually changes after childbirth

During pregnancy and childbirth, the body goes through significant changes. Hormonal shifts, increased pressure inside the abdomen, and the physical strain of delivery all affect the pelvic floor muscles. In some cases, medical interventions such as episiotomy may also play a role. The pelvic floor muscles act as a support system for the pelvic organs, including the bladder, uterus, and rectum. When their tone decreases or their function changes, the level of support changes as well.

According to studies, up to 50% of women experience at least one symptom of pelvic floor dysfunction in the first years after childbirth, from urinary leakage to early signs of pelvic organ prolapse. The most common complaints include stress urinary incontinence, for example during coughing or sneezing, and changes in the position of the cervix. Even less pronounced changes that are not always clinically diagnosed can still affect comfort, including when using menstrual products.

Why familiar menstrual products stop working

Leaks when using menstrual cups or discs

When pelvic floor support weakens, the vaginal walls can shift. In these conditions, standard cups and discs are not designed to adapt to this kind of pressure, so they may not fully open, may lose their shape, or fail to maintain a seal.

Pain, discomfort, and difficulty with urination or bowel movements

Most menstrual products are designed for what is considered a standard anatomy. After childbirth, the shape of the vagina, its angle, and the position of the organs may change. This can lead to uneven pressure from the product. For example, with bladder prolapse, the angle changes, and a product with the wrong shape or firmness can increase pressure and make urination more difficult. A similar effect can happen with the rectum, where pressure from the product may make bowel movements less comfortable.

Difficulty inserting or keeping the product in place

This is common for women who use tampons. Changes in vaginal anatomy can affect the usual angle, making insertion more difficult or requiring an uncomfortable position. Cups and discs may also not stay in place or may shift because they can no longer adapt to the changed anatomy, and pressure from surrounding organs can push them downward.

Dryness, irritation, and discomfort during menstruation

This is more often reported by women using pads. With weakened pelvic floor muscles, there may be less natural support and protection of the vaginal tissues. In these conditions, pads can increase dryness and irritation. In addition, menstrual blood and the pad surface can create an environment where bacteria grow more easily, which may contribute to imbalance of the vaginal flora.

Why I designed Leia Cup with postpartum anatomy in mind

Based on my clinical experience, conversations with my patients, and my own experience as a woman who has had a vaginal delivery, I realized that many products on the market simply do not take these changes into account. This led me to develop the Leia menstrual cup.

One of the first things I focused on was changing the shape, making it more anatomical and better adapted to a changed anatomy. This resulted in an asymmetrical design that makes insertion easier, even when the anatomy has changed.

Another important feature is the reinforced ring at the top of the cup, inspired by the support provided by medical pessaries. It helps distribute pressure more evenly and supports the vaginal walls, preventing the cup from collapsing or deforming. The medical-grade silicone is hypoallergenic, does not interact with the vaginal flora, and does not absorb bacteria.

A note from me to you

It's important to remember that if your menstrual products stopped working the way they used to after childbirth, it's not your fault, and it doesn't mean there is something wrong with your body. Your body has changed, and that is normal.

In many cases, the solution is not to give up on the products you prefer, but to find one that better matches your current anatomy and how your body feels now. You should not have to tolerate discomfort or settle for something that doesn't work. There is a solution — sometimes it just requires a different approach.
