Heavy menstrual bleeding (HMB) affects 1 in 3 women and can significantly impact quality of life. Despite its prevalence, there is no accessible and accurate diagnostic test.

The investigators aim to recruit approximately 130 participants across two study sites over three years, including people with and without HMB.
