Straightforward, judgement-free information about periods — what’s normal, what your options are, and when to see a doctor. Educational only, never a substitute for medical advice.
The basics
A menstrual cycle is counted from the first day of one period to the first day of the next. Cycles commonly run 21–35 days, and bleeding usually lasts 2–7 days. There’s a wide range of normal — what matters most is what’s normal for you, and noticing when that changes. Our guide to the four cycle phases explains what’s happening hormonally.
Your product options
| Option | Worn | Reusable | Good for |
|---|---|---|---|
| Period panties | Externally, as underwear | Yes, 2+ years | All-day comfort, overnight, teens, sensitive skin |
| Menstrual cup | Internally | Yes, several years | Heavy flow, long days, swimming |
| Menstrual disc | Internally | Reusable or disposable | Heavy flow, higher capacity |
| Cloth pads | Externally | Yes | Those who prefer pads but want reusable |
| Disposable pads/tampons | External / internal | No | Travel, no washing access, backup |
First periods
A first period often arrives between ages 10 and 15, and early cycles are frequently irregular for a year or two — that’s normal. Preparation removes most of the anxiety: a spare pair of period panties and a pouch in the school bag is usually enough. Our first period guide for teens and parents covers the conversation and the kit.
Period pain
Mild cramping is common and usually manageable with heat, gentle movement, hydration and rest. Some people find acupressure points helpful as a complement. Pain that stops you attending school or work, or that’s worsening over time, is not something to simply endure — see a doctor.
Hygiene without shame
Menstrual blood is not dirty. Washing with plain water is enough; internal washes and scented products can disturb natural balance and are best avoided. Change or wash products regularly, and store reusables dry.
When to see a healthcare professional
- Bleeding so heavy you soak through protection every hour or two
- Periods lasting longer than seven days, or cycles shorter than 21 or longer than 35 days consistently
- Severe pain that disrupts daily life, or pain that is getting worse
- Bleeding between periods or after sex
- No period by age 16, or a sudden stop when pregnancy isn’t the cause
