Introduction

Your period isn’t a clock, but sometimes, it goes way off schedule. If you’ve ever wondered why your cycle suddenly became irregular, you’re not alone. Almost every menstruator experiences delayed or early periods at some point.

This blog breaks down the most real, science-backed reasons behind menstrual irregularity and what you can do to regain balance.

1. Stress: The Biggest Hormonal Disruptor

High cortisol levels interfere with estrogen and progesterone production, leading to:

• Delayed ovulation
• Missed period
• Longer cycles

Try gentle movement, journaling, and cycle-friendly workouts. For comfortable exercise during periods, explore Revaa’s Activewear Range

2. PCOD & PCOS

These conditions disrupt ovulation, making cycles unpredictable. Common signs:

• Acne
• Weight gain
• Missed periods

3. Under-Eating or Sudden Weight Loss

Your body needs a minimum calorie intake to maintain happy hormones.

Low leptin levels = periods vanish or delay.

4. Excessive Exercise

Athletes or women with intense workout routines may experience amenorrhea.

Pair workouts with rest, and switch to period-friendly gear like Revaa Period Panties for comfort on heavy-flow days:

5. Thyroid Disorders

Both hypothyroidism and hyperthyroidism can cause:

• Heavy periods
• Light periods
• Missing periods
• A blood test provides instant clarity.

6. Birth Control Changes

Starting or stopping hormonal contraception can shift your cycle for 1–3 months.

7. Perimenopause

If you’re 35+, irregularity may simply be the start of the body’s natural transition.

8. Poor Sleep Schedule

Melatonin helps regulate reproductive hormones.

Sleep imbalance = period imbalance.

9. High Prolactin Levels

Often due to:

• Stress
• Certain medications
• Hormonal imbalance

10. Travel or Jet Lag

Changing time zones affects your circadian rhythm → affects hormones.

11. Nutrient Deficiencies

Low levels of:

• Iron
• Vitamin B12
• Vitamin D can delay your cycle.

12. Medical Factors

Conditions like fibroids, endometriosis, or pituitary issues can alter cycles.
