Why Do I Get So Angry and Irritable Before My Period?
You feel angry and irritable before your period because the late-luteal drop in estrogen lowers serotonin while cortisol reactivity rises, so your emotional threshold falls and small frustrations feel bigger. This premenstrual irritability is a real, hormone-driven response, not a character flaw, and it eases once your period starts.
The hormones behind your luteal phase
After ovulation the empty follicle becomes the corpus luteum and pumps out progesterone, which peaks mid-luteal then falls sharply if there is no pregnancy. That progesterone rise, followed by the late drop in both progesterone and estrogen, is behind PMS: lower serotonin, higher cortisol reactivity, more sebum and breakouts, water retention, cravings, and disrupted sleep in the days before your period.
- Progesterone rises and raises body temperature, appetite, and the need for rest.
- The late-luteal drop in estrogen lowers serotonin, driving mood swings, anxiety, and cravings.
- Progesterone stimulates oil glands, so jaw and chin breakouts flare.
- Cortisol reactivity and water retention climb, adding to bloating, tension, and poor sleep.
