Period Symptom Checker

A professional-grade menstrual health assessment tool aligned with Western gynecological guidelines (ACOG, NICE, WHO). Evaluate 35+ symptoms — including rare warning signs — across cycle phases, severity, and medical history. Receive graded relief plans (home care → referral), cycle-over-cycle comparison, and downloadable PDF reports with trend charts. For education only — not a substitute for clinical diagnosis.

  1. Enter cycle length (21–45 days) and select your current menstrual phase.
  2. Check relevant medical history — this adjusts risk thresholds.
  3. Set overall severity and tap all current symptoms (dashed borders = rare/warning signs).
  4. Results update in real time (disable auto-update to use Generate manually).
  5. Review assessment, graded relief plan, and abnormal alerts.
  6. Click Generate to save a record; use Download for PDF + trend chart.
  • ACOG: Periods lasting >7 days or soaking ≥1 pad/hour for several hours warrant evaluation for menorrhagia.
  • NICE NG73: Suspect endometriosis with cyclical pelvic pain, deep dyspareunia, or infertility — refer for laparoscopy consideration.
  • WHO: Iron supplementation recommended when anemia is confirmed alongside heavy menstrual bleeding.
  • DSM-5 / IAPMD: PMDD requires ≥5 premenstrual symptoms with functional impairment, confirmed over 2+ cycles.
  • ACOG Practice Bulletin: NSAIDs are first-line for primary dysmenorrhea; hormonal contraception reduces menstrual pain and flow.
  • Persistent severe cramps unrelieved by NSAIDs may indicate endometriosis or adenomyosis — seek gynecological evaluation.
  • Seek emergency care for sudden severe pelvic pain, fainting, chest pain, or leg swelling with shortness of breath (DVT/PE risk).
  • PMDD vs PMS: PMS is mild-moderate; PMDD causes severe mood disruption affecting work/relationships — treatable with SSRIs or hormonal therapy.
  • Nutrition: Calcium (1200 mg/day), magnesium (360 mg), and omega-3s show evidence for reducing premenstrual symptoms.

Menstrual Health Science

PMS vs PMDD

PMS affects up to 75% of menstruating people with mild-moderate physical/emotional symptoms in the luteal phase. PMDD (~3–8%) meets strict DSM-5 criteria: marked irritability, depression, or anxiety in the week before menses, resolving within days of onset, with documented functional impairment. PMDD responds to SSRIs, hormonal suppression, and CBT.

Evidence-Based Nutrition

Randomized trials support calcium (1200 mg/day) and vitamin B6 (≤100 mg/day) for premenstrual mood and bloating. Omega-3 fatty acids (1–2 g/day EPA+DHA) may reduce menstrual pain. Limit caffeine, alcohol, and refined sugar during the luteal phase. Iron-rich foods are essential when bleeding is heavy.
