- Period pain is a common symptom of the menstrual cycle, but it's not the only one.
- Some lesser-known symptoms include bowel disturbances and stabbing pains.
- Take a look at some of these symptoms below and signs that you should see a doctor.
Period pain is a common symptom of the menstrual cycle, affecting about 70% of young women – but it’s far from the only symptom.
Here are five lesser-known symptoms associated with the menstrual cycle – and what’s going on in your body to cause them.

1. Bowel disturbances (period poos)
Some people experience disturbances in their bowel habits leading up to their period and this commonly manifests as diarrhoea.
This happens because when you menstruate, your body releases a special chemical called prostaglandins. Prostaglandins help the uterus to cramp, which helps push menstrual blood out of the uterus and into the vagina so it can leave the body.
When you get period pain (especially if a person has endometriosis) a nerve in the back called the dorsal root ganglion is activated.
This can cause a range of symptoms, including back pain. This same process can make the bowel sensitive, which can lead to bowel pain or irritable bowel syndrome and contributes to changes in bowel habits like diarrhoea or constipation.

2. Stabbing pains
Sometimes, the arrival of your period can come with stabbing pains down the legs, abdomen or into the buttocks.
For some, this pain can shoot up the vagina or back passage.
This is related to the cramping that occurs when prostaglandins are released in the body and the nerve in the back (the dorsal root ganglion) is activated.
This can trigger spasms of the pelvic floor muscles (a group of muscles in the bottom of the pelvis that supports the bladder, bowel and uterus).
Seeing a pelvic health physiotherapist and learning to relax these muscles can help manage this type of pain.
3. Fatigue
It’s common to feel a bit run down around the time of your period. But for some people this can go beyond just regular tiredness.
A recent survey of 42 879 women showed about 70% experience this symptom. It is often described as feeling “exhausted”, “drained”, “tired”, “lethargic”, “worn out”, and/or “weak”.
Fatigue can be due to the brain’s experience of pain. We can measure changes in the brain when people experience pelvic pain. Ongoing pain signalling to the brain causes these changes, which results in extreme tiredness and sometimes headaches and nausea.
Having a good sleep schedule, exercising and eating well can help with fatigue.

4. Ovulation pain
Ovulation occurs when a mature egg is released from the ovary.
During this time, estrogen levels are high, and a lot of clear watery mucus is produced by cells in the cervix (which is why seeing extra clear watery mucus at this time is a sign ovulation is approaching).
Most people feel pretty good when their estrogen levels are high. But when the follicle the egg is in gets bigger near ovulation, the pressure of the follicle and its release can cause pain. This ovulation pain is sometimes called mittelschmerz, which is German for “middle pain”.
This can feel like a sharp, relatively short-lived stabbing pain in the lower abdomen on one side.

5. Mood changes
Between 50% and 70% of people who have periods experience changes to their mood leading up to or during their period.
But for between 1-5% of people, the impacts on mood can be more severe and may be associated with a condition called premenstrual dysphoric disorder (PMDD).
This occurs when people experience severe mood changes, anxiety or depression in the week before their period, which usually improves within a few days of their period starting.
When should you see a doctor?
Symptoms vary so much between people, there is a huge range of “normal” and it can be tricky to decide when to follow up with your doctor. But it is worth chatting to a GP if:
Your period pain interrupts daily activities such as work, school or caring responsibilities
The pain associated with your cycle is severe or changes
You have difficulty going to the bathroom, pain with urination or bowel movements or your bowel habits change
You feel emotionally or mentally overwhelmed
You experience pelvic pain at other times (outside of your period).
When these symptoms are severe, they can be due to conditions such as endometriosis.
EndoZone – an evidence-based website co-created with people affected by endometriosis – has a self-test for people trying to decide if their period symptoms require further medical care, and tips on how to describe them to a doctor.
