men·stru·al cycle

(mĕn′stro͞o-əl)
The series of bodily changes in women and other female primates in which the lining of the uterus thickens to allow for implantation of a fertilized egg. The cycle takes about a month to complete, with ovulation usually occurring around the midway point. If the egg produced is not fertilized, the lining of the uterus breaks down and is discharged during menstruation.

Exercise-associated MD may also occur at the subclinical level, consisting of luteal phase defects (LPD) or anovulation, that result in subtle hormonal changes not commonly detected by self-report (9) or distinguishable from eumenorrhea without hormonal assessment.

Essure[R] and endometrial ablation: clinical studies and case reviews of Essure with 118 Novasure[R] procedures
It is important to understand that menstrual dysfunction occurs along a continuum: women with anovulatory cycles may still have menstrual bleeding, and thus appear eumenorrheic, but their overall estrogen levels will be lower than women with true ovulatory eumenorrhea. This theory may begin to explain the borderline endothelial function seen in studies of oligomenorrheics and self-reported eumenorrheic athletes (Hoch et al., 2003).
