If your period is late, early, heavier, lighter, or just plain weird lately, stress might be the real culprit.
Your menstrual cycle isn’t just controlled by your ovaries it’s run by your brain. And when your brain thinks you’re under threat (hello, deadlines, burnout, and emotional chaos), reproduction drops to the bottom of the priority list.
Stress Delays Ovulation
When you’re stressed, your body releases cortisol. High cortisol tells your brain, “Now is not a great time to get pregnant.”
So ovulation gets delayed… or skipped entirely.
No ovulation = no period.
Late ovulation = late period.
It Can Change Your Flow
Stress can also:
- Make periods heavier
- Make them lighter
- Cause spotting
- Increase cramps and PMS
That’s because stress hormones interfere with estrogen and progesterone the hormones that control how much your uterine lining builds up and sheds.
Sleep & Stress Make It Worse
Stress ruins sleep, and poor sleep messes with hormones. It’s a cycle inside a cycle and it keeps feeding itself.
