When should you see a doctor about your period?
See a doctor about your periods if you soak a pad or tampon every 1 to 2 hours, bleed longer than 7 days, have pain that stops normal life, bleed between periods, after sex or after menopause, miss 3 periods in a row, or have cycles shorter than 21 days or longer than 35. Get urgent care for heavy bleeding with dizziness or severe sudden pain.
The checklist
| Sign | Why it matters |
|---|---|
| Soaking a pad or tampon every 1 to 2 hours, or doubling up | Heavy menstrual bleeding; can cause anemia and may point to fibroids, polyps, adenomyosis or a bleeding disorder |
| Bleeding for more than 7 days | Can mean heavy bleeding or a hormonal imbalance |
| Clots bigger than about 2.5 cm (1 inch) | A sign of heavy flow |
| Pain that stops work, school or sleep | Possible endometriosis, adenomyosis or fibroids |
| Pain getting worse over time | Secondary causes are more likely |
| Bleeding between periods or after sex | Infection, polyps, cervical changes, or contraception issues |
| Any bleeding after menopause | Always needs checking |
| No period for 3 months (and not pregnant) | Amenorrhea: stress, weight, PCOS, thyroid, prolactin or early menopause |
| Cycles under 21 or over 35 days, regularly | Irregular ovulation |
| Cycle lengths varying by more than 7 to 9 days | Irregular cycles worth investigating |
| No period by age 15 | Delayed puberty needs a check |
| Mood changes that disrupt your life each cycle | Possible PMDD or PME |
Red flags for endometriosis, adenomyosis and fibroids
- Endometriosis: severe period pain, pain before the period starts, deep pain during sex, painful bowel movements or peeing during your period, tiredness, difficulty getting pregnant.
- Adenomyosis: heavy, painful periods, often in your late 30s or 40s, with pelvic pressure or a swollen, tender lower belly.
- Fibroids: heavy or long periods, a feeling of fullness or pressure, needing to pee often, constipation, back pain.
More in when period pain is not normal, what counts as a heavy period and why your period stopped.
You're bleeding so heavily you soak through a pad every hour for several hours, or you feel faint, dizzy, breathless or have a racing heart; you have sudden severe pelvic pain; you have pain or bleeding with a positive pregnancy test; or you have high fever, a sunburn-like rash and vomiting while using a tampon or cup.
Mood symptoms count too
Periods aren't only about bleeding and pain. If you feel depressed, anxious, enraged or hopeless in the week or two before your period, every cycle, and it affects your relationships or work, that's a real medical reason to see a doctor. It may be PMDD, which is treatable. If you ever have thoughts of harming yourself, please reach out now: call your local emergency number, or in the US call or text 988. In the UK, Samaritans are on 116 123.
How to make the appointment count
- Bring the dates of your last three to six periods.
- Note how heavy each day was: how many pads or tampons, any flooding or clots.
- Rate pain and mood daily for at least two cycles.
- List medicines, contraception and supplements.
- Say plainly how it affects your life: days missed, sleep lost, plans cancelled.
