Why Does My Period Come Late? Causes, Symptoms & When to Worry
Have you ever asked yourself, Why does my period come late? A delayed period can cause stress and uncertainty. While pregnancy is often the first thought, there are many other reasons your cycle may be late, including stress, weight changes, and hormonal imbalances. In this guide, we’ll explore the most common causes, when to seek medical advice, and how to keep your menstrual cycle healthy and regular.
What Counts as a Late Period?
A typical menstrual cycle lasts around 28 days, but anywhere between 21 and 35 days is considered normal. Your period is late if it comes more than a week after your expected date or if you miss it altogether. Occasional delays are normal, but repeated late periods may indicate an underlying issue.
Main Reasons Why Your Period Comes Late:
High stress can affect the hypothalamus — the part of your brain that controls hormones. This can delay ovulation and shift your cycle. If you’ve recently gone through emotional stress, it might explain why your periods come late.
Weight & Lifestyle Changes:
Sudden weight loss, gain, or extreme dieting can disrupt hormone production and delay menstruation. Very low body fat or excessive exercise can even stop your periods entirely.
Hormonal Imbalances:
Conditions such as Polycystic Ovary Syndrome (PCOS) or thyroid disorders can cause irregular cycles. If your period does not come regularly and you also have acne, unwanted hair growth, or weight changes, consult a doctor.
Birth Control & Medications:
Hormonal contraceptives like pills, patches, or IUDs can change how often you get your period. Some women may skip cycles altogether. Certain medications for depression, blood pressure, or chemotherapy can also cause delays.
Perimenopause:
In your 40s, fluctuating hormone levels during perimenopause may cause late or missed periods, along with symptoms like hot flashes and sleep problems.
When to See a Doctor:
Seek medical advice if:
Your period is more than 60 days late
You have severe cramps without bleeding
You suspect pregnancy but tests are negative
There’s unusual discharge or other sudden changes
How to Keep Your Cycle Healthy:
Maintain a balanced diet, manage stress through meditation or yoga, and exercise moderately. Track your cycle with apps or a calendar so you can identify patterns and address changes early.
Conclusion:
If you’re wondering “why does my period come late?”, remember that occasional delays are common, but consistent changes should be checked by a healthcare professional. By maintaining a healthy lifestyle and monitoring your cycle, you can better understand your body and address problems before they become serious.
