This preparation is part of your menstrual cycle, which usually lasts 28 days but can be up to 35 days in some women. You should understand your uterus's role in depth so that you can care for it better, and also consult your doctor when you suspect anything unusual.

What Happens Inside Your Uterus Each Month?
Your body goes through various phases of the menstrual cycle, guided by hormones. The uterus prepares a favourable environment for a baby every month in case pregnancy happens.1. The Menstrual Phase (Day 1–5) – Clearing the Old Lining
- The first day of your period is the beginning of this phase.
- Your uterus sheds the lining (endometrium) from the previous month if no pregnancy occurred.
- You lose about 30–40 millilitres of blood on average during this time, though it can vary.
- This shedding allows the uterus to prepare for a fresh cycle.
2. The Follicular Phase (Day 1–13) – Building Up Again
- Your body releases a hormone called oestrogen after your period is over.
- High oestrogen signals the uterus to rebuild its lining by making it thicker and richer in blood vessels.
- This new lining again prepares itself to support a fertilised egg if conception happens.
- At the same time, your ovaries prepare eggs for ovulation.
3. Ovulation Phase (Day 14 in a 28-Day Cycle) – The Key Event
- Your ovary releases one mature egg around the middle of your cycle.
- Your uterine lining is now soft and rich with nutrients, waiting for the egg to arrive if it gets fertilised.
- This is the most fertile time in your cycle.
4. Luteal Phase (Day 15–28) – Preparing for a Guest
- This phase witnesses the surge in another hormone called progesterone.
- Your uterine lining becomes thicker and stickier so that the fertilised egg attaches itself securely to it.
- If fertilisation happens, the uterus continues to support the early stages of pregnancy.
- If conception does not happen, progesterone levels drop, which leads to the shedding of the lining and your next period.
Why Does the Uterus Go Through This Cycle?
Your uterus is a critical organ of the reproductive system, which prepares itself every month to receive a fertilised egg. The lining becomes thick with nutrients to support the growth of this egg. When pregnancy does not happen, it sheds the lining. This continuous cycle shows that your uterus is working in sync with the hormones.What Changes Might You Notice During This Cycle?
Your body undergoes various changes every month, giving you natural signs throughout your cycle.- The first sign is a clear and stretchy vaginal discharge, along with mild pelvic pain, or a slight increase in body temperature during ovulation.
- During the luteal phase, it is common to experience bloating, breast tenderness, mood swings, or food cravings (commonly known as PMS).
- Menstruation can lead to cramping, fatigue, and low back pain.
When Should You See a Doctor?
Knowing the difference between what is normal and when to seek medical help is crucial for your reproductive health.- Very heavy bleeding (soaking through a pad/tampon every 1–2 hours).
- Severe cramps that interfere with daily life.
- Irregular cycles are defined as those with a duration of less than 21 days or more than 35 days.
- No periods for more than 3 months if you are not pregnant.
- Unusual symptoms such as sudden pelvic pain or foul-smelling discharge.
How Can You Support Your Uterine Health?
You do not have to wait for pregnancy to take care of your uterus.Checklist for a Healthy Uterus
- Eat a balanced diet, including iron-rich foods (leafy greens, beans, lean meat), to support blood health.
- Water helps reduce bloating and improves nutrient absorption.
- Set time for gentle activities like yoga or walking to improve blood flow to your pelvic area.
- Manage stress, as high levels can affect your hormones and disrupt your cycle.
- Annual checkups with a gynaecologist can help detect problems early.
- Avoid smoking and excess alcohol because they can adversely impact your reproductive health.
Emotional and Social Aspects of the Uterine Cycle
Your cycle also affects your emotions, so it is common to experience mood swings due to hormonal changes during this time. Remember to ask for emotional support from your partner or family to cope with it. You can also get some rest or discuss the changes with your loved ones to help you manage your emotions during the menstrual cycle.Your uterus is always prepared for a possible baby every month by building a soft lining to receive a fertilised egg. It sheds the lining in the next period if pregnancy does not happen. The cycle is a strong sign of your reproductive function working well with your hormones, so caring for it is critical for your fertility.
