What Is the Menstrual Cycle?

The menstrual cycle is a monthly hormonal process that prepares the female body for pregnancy.

If pregnancy does not occur, the uterus sheds its lining through menstruation, also known as a period.

The cycle involves several hormonal changes controlled by:

Estrogen
Progesterone
Follicle-stimulating hormone (FSH)
Luteinizing hormone (LH)

Why Understanding Menstrual Cycle Phases Matters

Learning about the phases of menstrual cycle helps women:

Track ovulation and fertility
Identify irregular periods
Understand mood and energy changes
Manage PMS symptoms
Improve reproductive health awareness

It can also help healthcare providers detect underlying conditions such as PCOS or hormonal imbalances.

The 4 Stages of the Menstrual Cycle

The menstrual cycle has four main phases.

Phase	Typical Days	Main Hormones
Menstrual Phase	Day 1–5	Low estrogen & progesterone
Follicular Phase	Day 1–13	Rising estrogen
Ovulation Phase	Day 14	Luteinizing hormone surge
Luteal Phase	Day 15–28	Increased progesterone

1. Menstrual Phase Explained

During this stage, the uterus sheds its lining if pregnancy has not occurred.

Mood changes

Most periods last between 3–7 days.

Wellness tips:

2. Follicular Phase of the Menstrual Cycle

The follicular phase overlaps with menstruation and continues until ovulation.

During this phase:

The brain releases FSH

The uterus prepares for pregnancy

If pregnancy does not occur, hormone levels drop and menstruation begins again.
