Molimina
Molimina is a group of mild, predictable symptoms before a period that reflect normal progesterone activity. The word comes from the Latin for "exertions." Typical signs include slight breast tenderness, a sense of pelvic fullness, and mild water retention.
Small mood shifts and mucus changes before the period are also common. These symptoms occur because the corpus luteum, the gland left after ovulation, is producing progesterone. They fade when the period begins.
Molimina is a favorable sign. When it appears in a consistent pattern tied to peak day timing, it supports ovulation.1
A prospective study compared symptoms before the period with hormone tests. In that study, most women reported molimina whether or not they ovulated. For this reason, its presence cannot confirm ovulation on its own.2
Its value lies in the pattern charted over time, together with mucus signs and peak day. The presence or absence of molimina in a single cycle is much less informative.
Molimina differs from PMS. PMS is an excess of symptoms, with mood or physical symptoms severe enough to disrupt daily life. Molimina is the quiet signal of normal function after ovulation.
Suppressive medications can eliminate all awareness of the days before a period. This effect hides a signal that aids diagnosis.
In fertility charting, consistent molimina recorded with mucus signs and peak day builds a pattern over several cycles. Molimina may fade over later cycles, or it may never appear at all. Either finding warrants a closer look for anovulatory bleeding or a weakening luteal phase.
