Understanding menstruation, gently
Your bodyhas a rhythm.Let's learnto read it.
Flowguide is a calm, judgement-free guide to what really happens during your period — from the science of each phase to a simple tracker built for real life.
The four phases
A period isn't one event. It's a full circle of four distinct chapters.
Days 1 – 5
Menstrual phase
The uterus sheds its lining and menstruation begins. Hormone levels are at their lowest, which is why energy can dip. Rest is not weakness — it's biology asking for care.
Days 1 – 13
Follicular phase
Estrogen rises steadily as follicles in the ovaries mature. Many people feel a lift in mood, focus and physical energy as the body prepares to release an egg.
Around Day 14
Ovulation phase
A mature egg is released and travels toward the uterus. This is the most fertile window, often paired with peak energy, confidence and a rise in body temperature.
Days 15 – 28
Luteal phase
Progesterone rises to prepare the body for a possible pregnancy. If it doesn't happen, hormones fall again — sometimes bringing PMS — and a new cycle begins.
What you might feel
Your body speaks. Here's what it's often saying.
Cramps
Contractions of the uterus, felt in the lower belly or back.
Mood shifts
Hormone changes can heighten emotions and sensitivity.
Bloating
Water retention makes the belly feel fuller than usual.
Fatigue
Lower iron and hormone dips can leave you drained.
Cravings
The body reaches for quick energy — often sweet or salty.
Headaches
Shifting estrogen can trigger tension or migraines.

Myths & questions
Let's clear a few things up.
Feel better
Small rituals, real relief.
Warmth
A heat pack on the lower belly relaxes cramping muscles and soothes pain.
Hydrate
Water reduces bloating and supports steadier energy through the day.
Iron & greens
Leafy greens, lentils and lean protein help replenish what bleeding takes.
Gentle movement
Stretching and slow walks release endorphins — nature's painkillers.
Sleep
Extra rest helps hormones regulate and eases mood swings.

Knowing your pattern turns surprises into preparation.
