Emily, a 28-year-old runner in Colorado, thought she had everything figured out. She switched to a reusable menstrual cup, watched a few tutorials, followed the instructions carefully, and chose a well-known brand. On paper, everything checked out.
In reality, it did not.
Some days were fine. Others were not. Long runs made it worse. She adjusted insertion, tried different folding techniques, even timed removal more carefully. The problem kept coming back.
At some point, the question changed. It was no longer, “Am I using this correctly?” It became, “What if this just doesn’t fit me?”
That shift—away from technique and toward fit—is where most menstrual cup experiences either improve or stall. And it is exactly where MeLuna USA builds its entire approach.
