Understanding the Menstrual Cycle: Phases, Symptoms, and Common Myths
The menstrual cycle is a natural biological process that plays a crucial role in reproductive health. Yet, it’s often misunderstood, under-discussed, and surrounded by outdated myths. In this guide, we break down the menstrual cycle into its four main phases, explore common symptoms, and clear up misconceptions—empowering you with the knowledge you deserve.
What Is the Menstrual Cycle?
The menstrual cycle is the monthly hormonal cycle a person with a uterus goes through in preparation for pregnancy. It typically lasts between 21 and 35 days, though 28 days is considered average. The cycle is divided into four phases:
- Menstrual Phase
- Follicular Phase
Ovulation - Luteal Phase
1. Menstrual Phase (Days 1–5)
What Happens:
- This phase starts when menstruation (your period) begins.
- The uterus sheds its lining, leading to bleeding through the vagina.
- Hormone levels like estrogen and progesterone are low.
Common Symptoms:
- Cramps
- Fatigue
- Bloating
- Mood changes
2. Follicular Phase (Days 1–13)
What Happens:
- Overlaps with menstruation initially.
- The pituitary gland releases FSH (follicle-stimulating hormone), encouraging egg follicles to mature.
- Estrogen rises, helping rebuild the uterine lining.
Common Symptoms:
- Increased energy
- Clearer skin
- Improved mood
3. Ovulation (Around Day 14)
What Happens:
- A surge in LH (luteinizing hormone) triggers the release of an egg from the ovary.
- The egg travels down the fallopian tube, ready for fertilization.
Common Symptoms:
- Light spotting
- Increased libido
- Mild pelvic pain (mittelschmerz)
- Change in cervical mucus (clear and stretchy like egg whites)
4. Luteal Phase (Days 15–28)
What Happens:
- Progesterone levels rise to support a potential pregnancy.
- If fertilization doesn’t occur, hormone levels drop, triggering the next menstrual cycle.
Common Symptoms:
- PMS (premenstrual syndrome)
- Breast tenderness
- Irritability
Headaches
