Period Symptoms: Complete Guide to Physical & Emotional Changes
Menstrual cycle symptoms (PMS + menstrual phase) affect >90% of menstruators. Severity varies; tracking helps predict and manage.
Physical Symptoms
| Symptom | Timing | Mechanism |
|---|
| Cramps (dysmenorrhea) | 1–2 days before → first 2–3 days | Prostaglandins → uterine contraction, ischemia |
| Low back pain | With cramps | Referred uterine pain |
| Breast tenderness | Luteal phase (post-ovulation) | Progesterone → ductal growth; estrogen → stromal edema |
| Headache/migraine | Perimenstrual | Estrogen withdrawal → trigeminal sensitization |
| Acne flare | Luteal → menses | Androgen:estrogen shift → sebum ↑ |
| Bloating/water retention | Luteal | Progesterone → aldosterone → Na⁺ retention |
| Fatigue | Luteal + menses | Progesterone sedation, iron loss, sleep disruption |
| GI changes (constipation/diarrhea) | Perimenstrual | Prostaglandins act on gut smooth muscle |
Emotional / Cognitive Symptoms
- Mood swings, irritability, sadness, anxiety
- Brain fog, difficulty concentrating
- Sleep disturbance (insomnia/hypersomnia)

≥5 symptoms (1 mood + physical), severe functional impairment, luteal-phase only, confirmed by 2-month daily rating. Affects 3–8%. Treatment: SSRIs (continuous/luteal), OCPs (drospirenone), CBT, lifestyle.
Management Toolkit
- NSAIDs (ibuprofen/naproxen): Start 1 day before expected cramps; blocks prostaglandins.
- Hormonal OCPs: Suppress ovulation, stabilize hormones.
- Supplements: Magnesium 250–400 mg, B6 50–100 mg, calcium 1200 mg, vitamin D – modest evidence.
- Lifestyle: Aerobic exercise 150 min/wk, sleep hygiene, stress reduction, limit caffeine/alcohol/salt luteal phase.
- Heat: Heating pad/hot water bottle for cramps.
