Your menstrual cycle is more than just your period. It’s a sophisticated hormonal symphony that reflects your overall health. At North Delhi Uro & Gynae Clinic, we help women understand their menstrual cycle and recognize when something needs attention.
Average Cycle Length: 21-35 days (average 28 days) Menstrual Period Duration: 2-7 days (average 5 days) Menstrual Flow: 30-40 mL per period (average) Hormone Levels: Fluctuate throughout cycle
What’s “Normal” Varies: – Individual variation is huge – Your normal may differ from others – Consistency matters (same pattern each month) – Changes from your baseline warrant investigation
What Happens: – Uterine lining sheds – Blood, tissue, and fluid expelled – Duration: Average 3-7 days – Bleeding gradually decreases
Hormonal Status: – Estrogen: Low – Progesterone: Low – FSH: Beginning to rise – LH: Beginning to rise
Symptoms You May Experience: – Cramping (dysmenorrhea) – Bloating – Mood changes – Fatigue – Backache – Headache – Tender breasts
What’s Normal: – Bright red bleeding (may darken) – Passage of small clots – Flow heaviest first 2 days, tapering – Total blood loss 30-40 mL (less than 1/4 cup daily)
Red Flags (See Doctor): – Bleeding lasting >7 days – Soaking through 1+ pads per hour for several hours – Passage of large clots (>quarter size) – Severe pain – Systemic symptoms (fever, chills)
What Happens: – Pituitary releases FSH – FSH stimulates ovaries to produce follicles – Follicles produce estrogen – Endometrium begins thickening – Cervical mucus becomes wetter
Hormonal Changes: – FSH: Rising – Estrogen: Gradually increasing – Progesterone: Low – LH: Starts rising at phase end
Energy and Mood: – Energy levels increase – Mood improves – Confidence increases – Mental clarity improves
Physical Changes: – Skin may improve – Cervical mucus increases – Cervix rises and softens – Libido may increase
Duration: – Typically 13-14 days – Shorter in women with short cycles – Longer in women with long cycles
What Triggers Ovulation: – Estrogen reaches critical threshold – Triggers LH surge – LH surge triggers ovulation – Egg released 24-36 hours after LH surge
Hormonal Peak: – LH: Surge (most dramatic change) – Estrogen: Peak – FSH: Secondary surge – Progesterone: Beginning to rise
Fertile Window: – Starts 5 days before ovulation – Ends day after ovulation – Sperm can survive 3-5 days – Egg survives 12-24 hours – Intercourse every 2-3 days covers window
Ovulation Symptoms: – Mittelschmerz: Brief pain/cramps in lower abdomen – Cervical mucus peak (egg white consistency) – Slight temperature rise (detectable next day) – Breast tenderness – Increased libido – Slight mood elevation
Ovulation Prediction: – Ovulation predictor kits (detect LH surge) – Cervical mucus monitoring – Temperature tracking – Calendar method (less reliable) – Ultrasound monitoring (most accurate)
What Happens: – Empty follicle transforms to corpus luteum – Corpus luteum produces progesterone – Progesterone maintains endometrium – If no pregnancy, progesterone declines – Low progesterone triggers period
Hormonal Changes: – Progesterone: Rising then falling – Estrogen: Secondary rise then fall – LH and FSH: Low
Early Luteal Phase (Days 15-21): – Progesterone rising – Egg either fertilizing or degenerating – Energy high – Mood stable – Well-being
Late Luteal Phase (Days 22-28): Premenstrual Phase
Hormonal Changes: – Progesterone declining – Estrogen declining – Trigger for menstrual symptoms
Physical Symptoms: – Breast tenderness/swelling – Bloating – Weight gain (water retention) – Fatigue – Appetite increase (cravings) – Constipation or diarrhea – Headaches – Body aches
Mood Symptoms: – Irritability – Anxiety – Depression – Mood swings – Reduced patience – Sleep changes (too much or too little)
This is Premenstrual Syndrome (PMS): – Affects 75% of menstruating women – Moderate-severe symptoms: 25-30% – Typically starts 5-7 days before period – Resolves within 24 hours of period starting – Cyclical pattern is key feature
Severe Premenstrual Dysphoric Disorder (PMDD): – 3-8% of menstruating women – Debilitating mood/behavioral changes – Requires medical treatment – Different from PMS
Causes of Irregular Periods:
Hormonal Imbalances: – PCOS (most common) – Thyroid disorders – Prolactin elevation – Cortisol dysregulation
Reproductive Issues: – Uterine fibroids – Polyps – Adenomyosis – Intrauterine adhesions
Lifestyle Factors: – Extreme exercise – Low body weight – Rapid weight gain – Stress – Sleep deprivation – Lifestyle changes
Medical Conditions: – Diabetes – Bleeding disorders – Coagulopathy
Medications: – Hormonal contraceptives (can regulate or cause irregularity) – Antipsychotics – Anticoagulants – Corticosteroids
Life Stages: – Menarche (first period): Often irregular for 2-3 years – Perimenopause: Increasingly irregular – Pregnancy and postpartum: Disrupted cycling – Breastfeeding: Amenorrhea common
Consult Dr. Anju Bala For: – Sudden change from your normal pattern – Cycles <21 or >35 days consistently – Periods lasting >7 days – Heavy bleeding (soaking pads) – Amenorrhea (absent periods for 3+ months) – Breakthrough bleeding between periods – Postmenopausal bleeding – Painful periods interfering with activities – Concerning cycle changes
History and Physical: – Detailed menstrual history – Symptom assessment – Weight and lifestyle changes – Stress assessment – Medication review – Family history
Laboratory Tests: – Thyroid function (TSH) – Prolactin level – Testosterone (if signs of excess) – Pelvic ultrasound for structural issues – Hemoglobin (if heavy bleeding)
Imaging: – Transvaginal ultrasound – Hysteroscopy (if intrauterine pathology suspected)
Lifestyle Modifications: – Regular exercise (not excessive) – Stress management – Adequate sleep – Healthy weight – Nutrition optimization – Limit caffeine and alcohol
Hormonal Treatments: – Birth control pills (regulate cycles) – Hormonal IUD – Progestin therapy – Other hormonal options
Treatment of Underlying Cause: – PCOS management – Thyroid treatment – Weight normalization – Surgical removal of fibroids/polyps
Why Track? – Identify your baseline normal – Spot pattern changes early – Predict fertile window – Manage PMS symptoms – Share accurate information with doctor
What to Track: – Period start and end dates – Flow (light, medium, heavy) – Symptoms (cramps, mood, energy) – Ovulation signs – Any other notable changes
Tracking Methods: – Calendar or planner – Smartphone apps (Flo, Clue, Period Tracker) – Spreadsheet – Doctor-provided charts
The Cycle Reflects Health: – Regular cycles: Generally healthy – Irregular cycles: May indicate underlying issues – Cycle changes: Important diagnostic clues
Cycle and Fitness: – Training response varies by cycle phase – Follicular: Better for intense training – Luteal: Better for endurance, strength maintenance
Cycle and Nutrition: – Nutritional needs vary by phase – Iron needs increase during menstruation – Carbohydrate tolerance may vary – Caloric needs may increase luteal phase
Cycle and Mental Health: – Mood naturally fluctuates with cycle – Stress exacerbates PMS symptoms – Mental health affects cycle regularity – Treatment of mood disorders may help cycles
Lifestyle Approaches: – Regular exercise (reduces symptoms 50%) – Calcium supplementation (1,000-1,200 mg daily) – Vitamin D (2,000 IU daily) – Vitamin B6 (50-100 mg daily) – Magnesium supplementation – Reduce caffeine and salt – Adequate sleep
Medical Treatment: – SSRIs (selective serotonin reuptake inhibitors): – Luteal phase dosing most effective – Sertraline, fluoxetine, paroxetine options – 60% symptom improvement
Tracking and Timing: – Predict symptom onset – Plan important activities outside PMS window – Adjust work/social schedule if needed
What Dr. Anju Bala Recommends
“Understanding your menstrual cycle is key to women’s health. Every woman should know her baseline normal, track changes, and seek evaluation when something shifts. Your period is a vital sign—it tells us about your reproductive, hormonal, and overall health. Pay attention to it.”
