Common Reasons Your Period May Be Late

1. Pregnancy

• Pregnancy is the most common reason for a missed period.
• Even if you use protection, there is always a small chance.
  👉 If your period is late by more than a week, consider taking a home pregnancy test.

2. Stress

• High stress affects hormones like cortisol.
• This can delay or even skip a period.
  👉 Relaxation techniques like yoga or meditation can help.

3. Weight Changes

• Sudden weight loss or very low body fat can stop ovulation.
• Weight gain can disrupt hormone balance, causing delays.

4. Hormonal Imbalance (PCOS, Thyroid)

• Conditions like Polycystic Ovary Syndrome (PCOS) or thyroid issues can lead to irregular periods.
• Symptoms may include acne, excess hair growth, or sudden weight changes.

5. Medications & Contraceptives

• Birth control pills, IUDs, or certain medicines may affect cycle length.
• Some women notice lighter or skipped periods after starting new medication.

6. Perimenopause

• Women in their 40s or 50s may have irregular cycles as they approach menopause.

When to See a Doctor

• If your period is more than 3 months late without pregnancy.
• If you have severe pain, unusual discharge, or heavy bleeding.
• If you notice other symptoms like excess hair, sudden weight gain, or fatigue.

FAQs

Q: Can stress really delay my period?

A delay of 5–7 days is often normal, but longer delays may need medical attention.

Final Thoughts

A late period is usually not a serious issue. Pregnancy, stress, lifestyle, or health conditions can all play a role. If you are worried or notice repeated delays, consult a gynecologist for a proper check-up.

Key takeaway: Don’t panic if your period is late once in a while. But if delays keep happening, seek medical advice.
