In short

If your daughter's period pain is stopping her from going to school, sleeping, or doing the things she loves, that isn't "just a period". 

You can book a double appointment, bring a symptom diary, ask for specific tests, and request a gynaecology referral. 

If you feel dismissed, you're entitled to a second opinion. Severe period pain is treatable.

Why is my daughter's GP saying her period pain is normal?

Period pain in teenagers is often put down to "part of growing up", and sometimes it is. 

But if the pain is stopping your daughter from doing the things she'd normally do, it isn't normal, and it shouldn't be brushed off.

There are a few reasons GPs can underplay severe periods in teens:

• They may assume cycles will settle on their own (often true, but not always)
• Conditions like endometriosis take, on average, 7 to 9 years to diagnose in the UK
• Short appointment slots make it hard to get into the details
• Teens can find it hard to describe their pain in front of a stranger

That's not a reason to back off. luna hears from parents every day who've had to ask twice, three times, sometimes more, before their daughter was taken seriously.

How do I know if my daughter's periods are actually severe?

Heavy or painful periods are common in teens, but there's a clear line between uncomfortable and affecting her life. 

The NHS is clear: period pain that affects daily life should be looked at by a GP.

Signs her periods may need medical attention:

• She's missing school, sport, or social plans because of pain or bleeding
• Pain isn't relieved by paracetamol or ibuprofen
• She needs to change a pad or tampon every 1 to 2 hours, or doubles up products
• She's bleeding through clothes or sheets
• She's bleeding for more than 7 days at a time
• She's getting pain at other points in her cycle, not just during her period
• She's exhausted, dizzy, or pale (possible signs of anaemia)

A luna poll of 1,049 girls (September 2025) found that 70% have either skipped PE or wanted to because of their period. 

If your daughter is regularly missing things she'd usually love, that's worth taking seriously.

How can I prepare for my daughter's GP appointment?

Booking a double appointment and bringing a symptom diary are the two most useful things you can do. 

A standard 10 minute slot rarely gives enough time to get into period problems properly.

Before the appointment:

• Ask the receptionist for a double appointment when you book
• Ask for a female GP or a chaperone if your daughter would prefer
• Track 2 to 3 cycles in advance using a period app or paper diary
• Note pain levels on a 0 to 10 scale, what helps, and what it stops her from doing
• Write down which painkillers she's tried, how often, and whether they worked
• List other symptoms: tiredness, headaches, mood swings, bowel changes, pain during exercise

If English isn't your first language, you can ask for a translator when booking.

A simple symptom diary should capture:

• Cycle length: how many days from day 1 of one period to day 1 of the next
• Pain level: a daily 0 to 10 score, with notes on the worst days
• Days missed: school, PE, social plans, sleep
• What helped: painkillers (and how many), heat, rest, gentle movement
• Other symptoms: how often she's changing pads or tampons, tiredness, mood, headaches, bowel changes

What should I say at the GP?

Lead with how the periods are affecting your daughter's life, not just the pain itself. 

GPs are trained to listen for impact, and it's the impact (missed school, missed sleep, missed friends) that often unlocks the right care.

Things worth saying out loud:

• "Her periods are stopping her doing X, Y and Z"
• "We've tried paracetamol and ibuprofen and it isn't enough"
• "She's bleeding through pads in under 2 hours"
• "I'd like to know what tests we can do and what the options are"
• "If you don't think a referral is needed today, please can you tell me what would change that?"

It's fine for your daughter to lead the conversation if she wants to, and fine for her to want you in the room. Both are normal. 

A luna poll of 1,656 girls found that 1 in 4 say embarrassment or shame stops them from seeing a doctor: having a parent in the room can take that pressure off.

What tests or treatments should I ask about?

Investigations for painful or heavy menstrual periods can include a physical examination, blood tests, or scans. 

Treatment ranges from over the counter painkillers to hormonal contraception to surgery, depending on the cause.

Things a GP might offer or consider:

• A blood test to check for anaemia or thyroid problems
• A pelvic or abdominal ultrasound (less common in younger teens, but possible)
• Prescription strength painkillers, such as mefenamic acid
• Tranexamic acid tablets to reduce heavy bleeding
• The combined pill or hormonal coil to reduce pain and bleeding
• A referral to gynaecology if symptoms are severe or unexplained

You don't have to accept the first option. Shared decision making means you and your daughter have the right to ask: what are my options, what are the pros and cons of each, and how do I decide?

What conditions could be causing my daughter's severe periods?

Most teen periods settle into a more manageable pattern within a few years, but severe symptoms can be a sign of an underlying condition. 

Knowing the names can help you ask the right questions.

Conditions worth knowing about:

• Endometriosis: tissue similar to the womb lining grows outside the womb. Worth asking about if she has severe pain, pain at other times of the cycle, or pain on bowel movements
• Adenomyosis: womb lining tissue grows into the muscle of the womb. Worth asking about if she has very heavy and painful periods
• Polycystic ovary syndrome (PCOS): a hormonal condition affecting ovulation. Worth asking about if her periods are very irregular, very few, or absent
• Fibroids: non cancerous growths in or around the womb. Worth asking about if bleeding is heavy and prolonged (rarer in teens)
• Bleeding disorders: for example, von Willebrand disease. Worth asking about if heavy bleeding has been a problem since her very first period

According to Endometriosis UK, the average diagnosis time for endometriosis in the UK is 8 years and 10 months. 

If your gut is telling you something more is going on, that instinct is worth following and getting the ball rolling sooner rather than later.

How do I get a referral if the GP still won't help?

If your daughter's GP doesn't offer a referral and you feel her symptoms warrant one, you can ask directly: "Please can we have a referral to gynaecology?" 

You can also ask for a second opinion from a different GP at the same practice.

What to try if you're feeling dismissed:

• Ask for a second opinion from another GP at the same practice
• Ask for the conversation and your concerns to be recorded in her notes
• Ask the GP to explain in writing why a referral isn't being offered
• Contact your local Patient Advice and Liaison Service (PALS) for support
• Consider a private gynaecology appointment if accessible (many will write back to the NHS)

FAQ

At what age can a teen go on the pill for period pain?

There's no minimum age. The NHS says the combined pill can be prescribed to under 16s if a GP thinks it's appropriate, with consent assessed on an individual basis (sometimes called Gillick competence).

How long should I give a treatment before going back to the GP?

Usually around 3 cycles. If symptoms haven't improved, or have got worse, book another appointment. Treatments don't always work first time, and switching is common.

Can I go to the appointment with my daughter?

Yes. She can also ask to speak to the GP on her own for part of the appointment if she wants privacy. Both are completely normal, and the practice should accommodate.

What if my daughter doesn't want to talk to a doctor at all?

This is common. A luna poll of 1,656 girls found that 1 in 4 say embarrassment or shame stops them from seeing a doctor, and 1 in 5 say they avoid the doctor because they don't want a parent or carer to know. 

You can offer to do the talking, ask for a female GP, or help her write things down beforehand so she doesn't have to say them out loud.

Could her period pain be endometriosis?

It could be, especially if the pain is severe, started young, or happens at other times of the cycle. Endometriosis is hard to diagnose definitively without a laparoscopy, but a GP can begin investigations and refer her on.

A small note before you book

Your daughter is lucky to have someone in her corner. Severe periods aren't something teens should be expected to just live with, and the right care can change her life.

If you'd like to walk into the next appointment with everything you need, luna has a guide on how to track your daughter's period that makes preparing the symptom diary simple.

If your daughter is in severe pain, bleeding so heavily she feels dizzy or faint, or you're worried about her safety, contact NHS 111 or A&E.
