Why are my periods getting more painful?
Periods that get more painful over time are worth a doctor's check, because common causes include endometriosis, adenomyosis, fibroids, a copper IUD, or pelvic infection. Doctors call this secondary dysmenorrhea. Ordinary period pain usually starts in the teens and often eases with age, so new or steadily worsening pain, especially after 25, is a signal rather than something to just put up with.
Two kinds of period pain
| Primary dysmenorrhea | Secondary dysmenorrhea | |
|---|---|---|
| Cause | Prostaglandins making the uterus contract | An underlying condition in the pelvis |
| Usually starts | Within a year or two of the first period | Later, often after 25, or pain changes |
| Pattern | Day before and first 1 to 3 days of bleeding | Can start earlier, last longer, or happen outside periods |
| Over time | Often eases with age or after childbirth | Often gets worse |
| Pain relief | Usually works well | Often works less well |
If your periods hurt more than they used to, the key question is whether something has been added on top of normal cramps. See period cramps for what ordinary pain looks like.
Common reasons pain gets worse
- Endometriosis: tissue similar to the uterine lining grows outside the uterus. Pain often starts before bleeding, lasts longer, and may come with pain during sex, bowel movements or peeing. Diagnosis takes years on average, so speak up early.
- Adenomyosis: lining tissue grows into the muscle wall of the uterus. Typical in your 40s, with heavy periods and a bulky, tender uterus.
- Fibroids: non-cancerous growths that can cause heavier, longer and more painful periods, plus pressure or back pain.
- Copper IUD: can make periods heavier and more painful, especially in the first months.
- Pelvic inflammatory disease (PID): an infection, often from an untreated STI, which can cause ongoing pelvic pain, fever and unusual discharge.
- Coming off hormonal contraception: the pill often masks pain; stopping it can reveal your natural pattern, or a condition the pill was hiding.
- Perimenopause: heavier, irregular periods can bring more cramping.

What to bring to your appointment
- When the pain started getting worse, and how it's changed.
- Which days of your cycle hurt, rated 0 to 10, for two or three cycles.
- How heavy your periods are and how long they last.
- Pain with sex, bowel movements or peeing, if any.
- What you've tried, and whether it helped.
- Days missed from work, school or plans because of pain.
Period pain is getting worse over months or years, stops you working, studying or sleeping, doesn't respond to anti-inflammatory pain relief, starts before your period or lasts after it, or comes with heavy bleeding, pain during sex, bleeding between periods, fever or unusual discharge. Get urgent care for sudden severe pelvic pain or pain with a positive pregnancy test.
Pain and mood
Months of worsening pain wear people down. Dreading your period, cancelling plans and sleeping badly can all feed into low mood and anxiety. You don't have to put up with it, and a pain record often helps you get taken seriously. Read when period pain is not normal for a clear checklist.
Frequently asked questions
Is it normal for period pain to get worse with age?
Not usually. Ordinary period pain tends to ease with age. Pain that's getting worse should be checked.
Can stress make period pain worse?
Stress can make pain feel worse and harder to cope with, but it doesn't explain pain that steadily worsens over months.
Why are my cramps suddenly worse this month?
A single bad month can follow stress, illness or a heavier period. If it happens again, or you could be pregnant, see a doctor.
Can an ultrasound show endometriosis?
Sometimes, especially cysts on the ovaries, but small patches often don't show. A normal scan doesn't rule it out.
