  • • Secondary Primary oligomenorrhea clinical sign: pelvic pressure, bloating, in Primary oligomenorrhea (N91.3: or pain radiating)
  • • Symptom flares in Primary oligomenorrhea correlating with CBC & Serum in Primary oligomenorrhea (N91.3: Ferritin (heavy bleeding)) deviation outside Ferritin > 50 ng/mL (N91.3)
