The menstrual cycle is one of the most important indicators of overall health.

Yet many women are unsure what is actually normal.

What a healthy cycle looks like

A typical cycle:

• Occurs every 24–35 days

• Includes ovulation

• Has a luteal phase of around 12–14 days

• Features manageable symptoms

What is common but not optimal

Many symptoms are often dismissed as “normal,” including:

• Significant pain

• PMS or mood changes

• Irregular cycles

• Heavy bleeding

These are signs that something may be out of balance.

Why the cycle is a vital sign

In clinical practice, the menstrual cycle gives us insight into:

• Hormonal health

• Nutrient status

• Stress levels

• Overall system function

The impact of lifestyle and stress

Cycle disruption can be influenced by:

• Chronic stress

• Poor sleep

• Nutrient deficiencies

• Over-exercise or under-eating

What the pill actually does

The oral contraceptive pill suppresses ovulation.

The bleed you experience is not a natural menstrual cycle, but a withdrawal bleed triggered by hormone changes.

The takeaway

Your cycle is information. When you understand what it’s telling you, you can start addressing the underlying drivers.
