Each tool is plain-language and judgement-free. They support informed choices and good conversations with a provider, they don't replace medical care.
Know your rhythm
Menstrual Cycle Tracker
Estimate your next three periods and your fertile windows.
A menstrual cycle is counted from the first day of one period to the first day of the next, most often somewhere between 21 and 35 days, with 28 being a common average. Enter the first day of your last period and your usual cycle length, and this tool maps out what to expect next.
Educational only, not a medical diagnosis. Cycle timing is an estimate and isn't reliable contraception on its own.
Find your most fertile days
Ovulation Calculator
Estimate the day your ovary is most likely to release an egg.
Ovulation usually happens about 14 days before your next period starts, not 14 days after your last one. So in a longer or shorter cycle, the timing shifts. This tool works it out from your cycle length for you.
Educational only, not a medical diagnosis.
Plan around your fertile window
Fertility Window Calculator
See the handful of days when conception is most likely.
An egg lives for about a day, but sperm can survive inside the body for up to about five days. That means the "fertile window" spans roughly the five days before ovulation plus the day itself. Whether you're hoping to conceive or simply want to understand your body, this shows those days.
Educational only, not a medical diagnosis. Fertility-awareness timing should not be relied on alone to prevent pregnancy.
Estimate your due date
Pregnancy Due Date Calculator
Estimate when your baby is due from your last period.
This uses Naegele's rule, the standard method midwives use: count 40 weeks (280 days) from the first day of your last period. It's an estimate; only about 1 in 20 babies arrives exactly on the due date, and most come within a couple of weeks either side.
Educational only, not a medical diagnosis. Confirm dating with an ultrasound and your antenatal clinic.
How far along are you?
Pregnancy Week Calculator
Find your current week and trimester.
Pregnancy is counted in weeks from the first day of your last period, so you're already counted as "2 weeks" around the time you conceive. Trimesters are roughly: first (weeks 1–12), second (weeks 13–27), and third (weeks 28 to birth).
Educational only, not a medical diagnosis. Book antenatal care early and ask about HIV testing and prevention in pregnancy.
A healthy pregnancy, step by step
Safe Motherhood Checklist
Tick off the milestones that protect you and your baby.
These are the building blocks of a safe pregnancy and birth. Work through them with your antenatal clinic, tick each one as you go.

- Attend all your scheduled antenatal visits
- Take an HIV test in pregnancy and know your status
- Take folic acid and iron supplements as advised
- Make a birth plan and arrange a skilled birth attendant
- If living with HIV, start PMTCT to protect your baby
- Attend your postnatal check after delivery
- Discuss family planning for after the birth

Get to know your normal
Breast Health Awareness Guide
Simple awareness habits that help you notice change early.
Know what's normal for you
Breasts naturally feel different at different points in your cycle, often fuller or tender before a period. The goal isn't to find a problem; it's to learn what's usual for your body so you can notice when something changes.
Build a monthly self-awareness habit
Once a month, look and feel, in the mirror and lying down or in the shower. Use the flat pads of your fingers, cover the whole breast and up into the armpit, and choose a regular time (a few days after your period is a good anchor).
Signs to see a clinician
- A new lump or thickening in the breast or armpit
- Change in size, shape, skin texture (dimpling or puckering)
- Nipple changes, pulling inward, rash, or discharge (especially with blood)
- Persistent pain in one spot, or redness and swelling that doesn't settle
Clinical breast exam
Ask a nurse or doctor to examine your breasts as part of routine check-ups, and discuss when screening (such as mammography) is right for your age and history.
Educational only, not a medical diagnosis. See a healthcare provider about any change that worries you.
Stay ahead of cervical cancer
Cervical Cancer Screening Reminder
Set a calendar reminder for your next screening.
Cervical screening looks for early changes before they become cancer. Depending on the test available, screening is usually repeated every few years:
- HPV test, often every 5 years if negative
- VIA (visual inspection), commonly offered every 1–3 years
- Pap smear, typically every 3 years
Educational only, not a medical diagnosis.
Compare contraceptive methods
Family Planning Method Comparison
How common methods work, how well, and what to weigh up.
| Method | How it works | Effectiveness | Notes |
|---|---|---|---|
| Implant | Small rod under the skin releasing hormone | Over 99% | Lasts 3–5 years; nothing to remember daily |
| IUD, copper | Device in the uterus; copper stops fertilisation | Over 99% | Hormone-free; lasts up to 10–12 years; can be used as emergency contraception |
| IUD, hormonal | Device releasing low-dose hormone in the uterus | Over 99% | Often lightens periods; lasts 3–8 years |
| Injectable | Hormone injection every 1–3 months | About 94–99% | Private; return to fertility can be slower |
| Pill | Daily hormone tablet | About 91–99% | Needs daily routine; quick return to fertility |
| Condoms | Barrier worn on the penis or inside the vagina | About 79–98% | Only method that also protects against STIs and HIV |
| Emergency contraception | Pill (or copper IUD) after unprotected sex | Best within 72h (some 120h) | Backup, not for regular use; copper IUD up to 5 days is most effective |
| Natural / fertility awareness | Tracking cycle to avoid fertile days | About 76–95% | Hormone-free; needs careful tracking and a regular cycle |
Educational only, not a medical diagnosis. A provider can help you choose what fits your health and life.
What might suit you?
Contraceptive Decision Guide
Five quick questions, one at a time, then talk it through with a provider.
Would you prefer something you don't have to think about daily?
Are you open to a long-acting method (implant or IUD)?
Do you plan to wait a while before any future pregnancy?
Do you also want protection against STIs and HIV?
How important is privacy (nothing visible, nothing at home)?
Educational only, this guide reflects your preferences and does not prescribe a method. Choose with a qualified provider.
Understanding menopause
Menopause Information Hub
What to expect, and when to reach out for support.
What it is
Menopause is when periods stop for good, usually between the ages of 45 and 55. It's confirmed after 12 months with no period. The years of change leading up to it are called perimenopause, when hormone levels shift and cycles often become irregular.
Common changes
- Hot flushes and night sweats
- Irregular or changing periods, then none
- Sleep changes, mood shifts, brain fog
- Vaginal dryness and changes in sex drive
- Joint aches and changes in skin and hair
When to seek care
See a provider if symptoms disrupt your daily life, if you have very heavy bleeding, or any bleeding after menopause has been confirmed, that always needs checking. Ask about options for managing symptoms, plus bone and heart health, which need extra attention after menopause.
If you're living with HIV
Menopause can arrive a little earlier and some symptoms may feel stronger. Keep taking your treatment, stay engaged with your care team, and mention menopause symptoms so support can be tailored to you.
