Diagnosis of Heavy Menstrual Bleeding Using Alternative Period Products

This study is currently closed to enrollment.

This study may help us compare the use of menstrual cups and period underwear to disposable pads and tampons in people who have heavy periods.

We are seeking people with heavy periods 18 years or older to participate in a study using alternative period products (menstrual cups and period underwear). In order to diagnose heavy periods, healthcare providers typically depend on information like how often disposable pads or tampons are changed. Many people prefer to use menstrual cups and/or period underwear, so we need more information on how frequent individuals with heavy periods empty cups or saturate underwear. Interested individuals will participate for two full menstrual cycles. During the first cycle, individuals will manage menses as they typically do with disposable pads or tampons and report on the frequency of change, leaking, etc. During the second menstrual cycle, participants will be randomly assigned (like the flip of a coin) to use either a menstrual cup or period underwear on the heaviest days of the cycle and will report the same information on the frequency of change, leaking, etc.
