Inclusion criteria

* Signed informed consent * Reports subjectively heavy menses for most menses when not using hormonal contraception or a copper IUD * Healthy females 18-50 years old, inclusive, at the time of enrollment * Able to read and write, as determined by study personnel * FSH value ≤30 mIU/mL at screening * Typical menstrual cycle length of 21-35 days with variation from cycle to cycle of typically 5 days or less * Has menstrual blood loss in 2 of the 3 cycles during the Screening Phase with ≥ 80 mL per cycle as measured by the AH method * Uterine sound depth of ≥5.5 cm * Willing to comply with study visit schedule and assessments, including sanitary product collection and diary completion requirements * Documented (i.e., printed report) Pap testing, regardless of subject's age, and any indicated evaluation/treatment that demonstrates no need for further evaluation during the course of study participation (i.e., within 10 months after consent) * Planning to reside within a reasonable driving distance of a research site (approximately 150 miles) for duration of study participation * Willing to use a medication other than a NSAID as first-line treatment for any pain condition during the duration of study participation * Willing to abstain from heterosexual intercourse or use acceptable contraception during the screening phase; acceptable contraception includes male or female permanent contraception, withdrawal (if has been using as current method prior to screening) or a barrier method * If previously pregnant, at least one subjectively heavy menses prior to screening

Exclusion criteria

* Currently pregnant * Planning to attempt to become pregnant during the screening and treatment phases of study participation (i.e., up to approximately 11 months after consent) * Currently lactating or not having a subjectively heavy menses since discontinuation of lactation prior to screening * Clinical diagnosis of perimenopause (in the opinion of the investigator) based on one or more of the following: changes in menstrual regularity (e.g., shorter, longer, absent, irregular), hot flashes, sleeping disorder, or changes in mood (e.g., depression, nervous tension, and irritability) within 3 months prior to or during the screening period * Screening blood laboratory value outside of the normal range that, in the opinion of the investigator, requires treatment or further work-up (i.e., are considered clinically significant) * Has poor venous access or significant history of inability to have blood samples drawn * Body habitus or history of lower genital tract abnormalities or prior surgeries which may prohibit proper visualization of the cervix or not allow the uterus to be appropriately instrumented * History of bicornuate uterus or any other abnormality of the uterus resulting in distortion of the uterine cavity or cervical canal incompatible with insertion * Prior (documented within 6 months) or baseline study ultrasound examination demonstrating: * A congenital or acquired uterine anomaly that distorts the uterine cavity or cervical canal incompatible with insertion; * Endometrial polyps (unless previously removed), * Fibroids meeting any of the following criteria: Distort the uterine cavity or cervical canal incompatible with insertion; Submucosal location; Exceeding 2 cm in the greatest dimension for any individual fibroid;
