What does a period feel like? Do periods hurt?
The short answer
For most people a period feels like a dull, heavy ache low in the belly, sometimes spreading to the lower back and thighs, plus a sense of wetness or warmth as blood leaves the body. The ache is usually strongest in the first day or two and then fades. Some people feel almost nothing; some have pain that needs painkillers for a day or so. Pain that stops you doing normal things is not something to put up with; it has causes that can be treated.
Do periods hurt?
Most do, a little, and the NHS says period pain is common. The cramping comes from the womb squeezing to shed its lining. ACOG estimates more than half of people who menstruate have some pain for a day or two each month. For most it is mild to moderate and eases with heat, movement or over-the-counter pain relief. A minority have pain that is severe; that is called dysmenorrhea and is worth a doctor’s visit. See period pain: what’s normal, and when it isn’t.
What a period feels like, day by day
The day before: sore breasts, bloating, low mood, mild cramps or a backache. Some people have a day of pink or brown spotting. See signs your period is coming.
Day 1 to 2: the heaviest flow and the strongest cramps for most people. You may feel a gush when standing up after sitting or lying down, which is normal: blood pools while you’re still. Tiredness and loose stools are common.
Day 3 to 5: flow lightens, cramps usually stop, energy returns.
Last day or two: light flow, often brown as the blood is older and leaves more slowly.
Most periods last 2 to 7 days, about 5 on average.
What the bleeding is like
- Colour: bright red on heavy days, darker red or brown at the start and end. All normal.
- Clots: small clots (smaller than a coin) on heavy days are normal.
- Amount: the whole period is roughly 2 to 3 tablespoons of blood, even though it looks like more. Changing a pad every 3 to 4 hours is typical on heavier days.
- Texture: it is thicker than blood from a cut, because it contains lining tissue as well as blood.
Feelings and energy
Hormones drop just before and during the period, which is why tiredness, irritability, low mood or feeling weepy are common for a day or two. Some people actually feel calmer or clearer once the period starts. Mood symptoms that are severe every month are worth raising with a doctor; see PMS, PMDD and mood.
What a first period feels like
Often lighter and shorter than later ones, with brown or pink spotting rather than red flow, and sometimes no cramps at all. Our guides cover how long a first period lasts and first periods: what to expect.
What is not normal
See a doctor if you have:
- pain that stops you going to school or work, or isn’t helped by painkillers
- pain that has got worse over several months
- bleeding that soaks a pad or tampon every 1 to 2 hours, or clots bigger than a coin
- periods that last more than 7 days
- bleeding between periods or after sex
- feeling faint, dizzy or breathless, which can mean low iron
Knowing your own normal
A period feels different for everyone, and even for the same person from month to month. Noting the date, how heavy each day was and whether it hurt builds a record of your own normal, which is what makes a real change easy to spot and easy to describe to a doctor. Cycella logs that in a few taps with no account, and keeps it on your phone; the app is free on Google Play for Android.
