Seeing a doctor
When should I see a doctor about my period?
See a doctor if your periods are under 21 or over 35 days apart, last more than 7 days, stop for 3 months, or come with new pain or bleeding. Get help the same day for severe pain that painkillers don’t ease, or a missed period with unusual bleeding and tummy pain.

Which signs need help today?
- Period or pelvic pain that’s severe or worse than usual, and painkillers haven’t helped.
- A missed period with unusual bleeding and pain anywhere in your tummy.
- Thoughts of suicide, with PMS or at any time: call your local emergency number or a support line now.
Which signs are worth booking an appointment for?
- Periods that come less than 21 or more than 35 days apart, or last more than 7 days.
- 3 missed periods in a row, or no periods by 15.
- Heavy periods that affect your life.
- Pain that stops your usual day, or pain during sex or when peeing or pooing.
- Bleeding between periods or after sex.
- PMS that lifestyle changes haven’t helped.
- Any bleeding after menopause.
Frequently asked questions
Should I see a doctor for irregular periods?
The NHS says to see a GP if your periods are irregular. Irregular means the gap between periods is less than 21 or more than 35 days.
What should I bring to the appointment?
Your dates, your symptoms and your questions. Preparing for an appointment has a short list.
Is it worth going if my symptoms seem mild?
Yes. A change in your periods doesn’t necessarily mean something is wrong, but the NHS says it does need looking into.
