This menstrual cycle mood swings chart maps how your mood tends to move through the month, phase by phase, with the hormone shift behind each stretch. The pattern is real and it is not random: mood tends to lift while estrogen rises, settle while progesterone takes over, and dip when both fall before your period. Below is the chart, the science behind it, and how to turn it into a tool for your own cycle.

The menstrual cycle mood swings chart

A menstrual cycle mood swings chart maps each phase of the cycle to the mood most people notice in it and the hormone shift driving it. Days below assume a 28-day cycle counted from day 1, the first day of your period, and shift with your own cycle length.

If a row does not match your month, that is information, not failure. The chart is the average pattern, and your own tracked pattern beats it every time.

The hormones behind the chart

Two hormones do most of the driving. According to Cleveland Clinic, estrogen rises through the follicular phase, which begins on day 1 of your period and ends at ovulation, and progesterone rises through the luteal phase, which runs from about day 15 to day 28. If there is no pregnancy, both drop, and your period starts.

The two curves under the chart: mood tends to track the rises, and the late-cycle dip tracks the falls.

That is the whole logic of the chart in one image. The rises feel like lift and steadiness, and the sharp late-cycle fall is the stretch where patience gets thin. For a day-level version of that second half, our guide to the luteal phase day by day walks days 15 to 28 one stretch at a time.

When do mood swings peak in the cycle?

The days just before your period, the Pre-Storm window on the chart. The Office on Women’s Health notes PMS symptoms typically land in the five days before a period and end within four days after it starts, fading as hormone levels begin rising again.

The NHS lists mood swings, feeling depressed or irritable, and feeling upset, anxious or emotional among the most common PMS symptoms. If that week reliably brings a specific flavour of hard, like anxiety, our guide to anxiety before your period goes deeper on it.

How to use the chart

When is it more than the chart can explain?

Cycle-linked mood swings are common and workable for most people. Sometimes, though, the pattern is pointing at something that deserves treatment rather than tracking, and Cleveland Clinic describes PMDD as exactly that: a severe, recognised, treatable condition.

None of this is a character flaw, and the full story of causes and coping lives in our guide to period mood swings. A chart cannot fix a hard week, but it can prove the week is a pattern, and a pattern is something a doctor can work with.
