The Biology of Menstruation

Every month, your ovaries release an egg (ovulation), and your uterus builds a soft lining (endometrium) to prepare for a possible pregnancy. If the egg isn’t fertilized, that lining breaks down and flows out as blood and tissue—your period.

Hormones at work:
• Estrogen thickens the uterine lining.
• Progesterone stabilizes it.
• When both drop, bleeding begins.

Cycle length:
• Typical range: 21–35 days.
• Bleeding lasts 2–7 days.

Managing Your Period

Hygiene & Comfort
• Change pads/tampons every 4–6 hours.
• Wash with mild soap and water.
• Wear breathable cotton underwear.

Pain Relief
• Gentle exercise or stretching.
• Warm water bottle on your belly.
• Over‑the‑counter painkillers as needed.

Tracking
• Use a calendar, app, or journal.
• Note your flow, mood, and symptoms—this helps you anticipate future periods.

Emotional Well‑being & Support

It’s normal to feel a mix of excitement, nervousness, or even pride. Talking helps:

- Mom, sister, or friend: share your experience—chances are they’ve been there too.

- Teacher or counselor: they can provide privacy and permission to step away if you need it.

- Mira AI assistant (if using SHELY): ask questions anytime, no judgment.
