Periods

Day one is the first day of bleeding

The menstrual cycle is counted from the first day of a period, not the day bleeding stops.

A cycle is measured from the first day of one period to the day before the next begins. Cycles of roughly 21 to 40 days are common, and they are often irregular in the first years after periods start.

Severe period pain is not something to simply endure

Pain that stops school, work or sleep deserves medical attention.

Period pain is common, but pain that disrupts daily life can be linked to conditions such as endometriosis, adenomyosis or fibroids. Keeping a simple symptom diary helps a GP take the picture seriously.

Periods

Heavy bleeding has a definition, and treatment

Soaking through protection every hour or two, or passing large clots, should be checked.

Heavy menstrual bleeding can cause tiredness and iron deficiency anaemia. It is treatable, and a GP can investigate causes rather than leaving someone to manage alone.

NHS: Heavy periods

Menopause

Menopause is confirmed after twelve months

Menopause is reached after 12 consecutive months without a period, with no other medical cause.

The years of changing hormones beforehand are perimenopause, and symptoms often begin then. In the UK, menopause usually happens between 45 and 55, with an average around 51.

Lesser-known facts

Menopause symptoms are not only hot flushes

Anxiety, low mood, brain fog, joint pain, palpitations and sleep problems are all recognised.

Because these symptoms look like many other things, they are often missed or misattributed. Naming them clearly is one of the quickest ways to help someone get the right support at work or from a GP.

Lesser-known facts

Early menopause happens, including under 40

Premature ovarian insufficiency affects around 1 in 100 women under 40.

It can also follow surgery, chemotherapy or radiotherapy. Younger people are rarely told this is possible, which delays diagnosis and support at exactly the point it matters most.

Lesser-known facts

Periods can still be irregular for years after they start

Irregular cycles in the first couple of years are usually part of settling into a pattern.

Knowing this prevents unnecessary fear, while still leaving room to seek advice if periods stop, become very heavy, or are extremely painful.

Periods

Period products have a safe wear time

Tampons should be changed regularly and not left in longer than the packet advises.

Practical product knowledge — pads, tampons, cups, discs and period underwear — is part of every session we run, because confidence with products is what keeps young people in the classroom.

Support & guidance

Menstrual health belongs in the workplace conversation

Menopause and heavy periods are common reasons experienced staff reduce hours or leave.

Simple adjustments — uniform flexibility, temperature control, breaks, understanding managers — retain people. We help employers put language and policy around that.
