The PMS Belt

Meet the Inventor: Megan Nuffer

The PMS Belt was invented by Megan Nuffer, entrepreneur and founder of Her Operational Excellence. Inspired by her wife Melissa's experience with debilitating menstrual pain caused by endometriosis, Megan set out to create a portable solution that combined heat, vibration, and adjustable pressure into one wearable device.

What began as an act of love became a journey through product development, entrepreneurship, and a mission to give women more options for managing menstrual discomfort.

It started with one really painful night.

In 2018, my wife Melissa woke up around 2 a.m. in excruciating menstrual pain from endometriosis. This woman was an athlete, she has had 6 knee surgeries, 10+ concussions and more. She can endure pain. However, when she started her period each month, the pain was unbearable. 

She ran out of her prescription ibuprofen and couldn't handle the pain. She had to leave the house in the middle of the night to go to the store.

The entire time she was gone, I searched the internet for possible solutions. There had to be something out there! WRONG!  

I couldn't stop thinking:

Why, when period pain is so common, were our options still so limited to birth control or pain pills?

I didn't set out to create a company that night.

I set out to create something that could help my wife.

We began developing a wearable solution that combined the things that brought her comfort — heat, vibration and pressure — into one portable belt.

And then something funny happened.

The Sisterhood of the Traveling Belt

Friends tried it.

Then family.

Then someone else wanted to borrow it.

And suddenly our prototype was being passed from woman to woman whenever somebody's period showed up.

We jokingly started calling it “The Sisterhood of the Traveling Belt.”

But underneath the joke was something much bigger:

If the women in our lives needed this, how many other women did too?

That little traveling prototype eventually became The PMS Belt.

🔥 HEAT — Turn up the comfort

The PMS Belt uses 11 heating nodes across the lower abdomen to provide targeted warmth where cramps are often felt most.

Heat therapy has also been studied specifically for menstrual pain, with systematic reviews finding evidence that it can reduce pain associated with primary dysmenorrhea.

〰️ VIBRATION — Like a massage you don't have to hold

Two targeted vibration modules provide soothing massage across the lower abdomen, giving you another layer of comfort without having to sit there rubbing your stomach yourself.

🤍 PRESSURE — That “curl up in a ball” feeling

There's a reason so many of us instinctively curl up, hug a pillow, or apply pressure when we're cramping.

The adjustable design lets you control how snugly The PMS Belt sits against your lower abdomen, so you can find the amount of compression that feels comfortable to you.

Period pain isn't rare. It's incredibly common.

A 2026 systematic review that included 336 studies across 70 countries estimated the global prevalence of dysmenorrhea at 71.3%. 

And yet so many people still plan work, school, travel, workouts and everyday life around their periods.

We think they deserve better options.

The PMS Belt isn't about pretending periods don't happen.

It's about giving you another tool to help you feel more comfortable when they do.
