12 Weeks Pregnant: Complete Checklist
Twelve weeks is a genuine milestone — the end of the first trimester is close, miscarriage risk drops significantly from this point, and there's a real sense of things becoming more official. Here's what's worth thinking about this week.
Scans and appointments
- Attend your 12-week (dating) scan. This confirms your due date, checks your baby's development, and may include combined screening for Down's, Edwards', and Patau's syndromes if you've chosen to have it.
- Ask about nuchal translucency measurement. If you're having combined screening, this is measured during the same scan — your sonographer or midwife can explain what it involves.
- Some people try nub theory for fun. Based on the angle of a small structure visible on the dating scan, this is a popular but non-diagnostic guessing game about your baby's sex — it's roughly as accurate as a coin toss when attempted by non-professionals, so treat it as entertainment rather than a reliable prediction.
Admin and finances
- Apply for your maternity exemption certificate (MatEx). This gives you free NHS prescriptions and dental care throughout pregnancy and for 12 months after birth — your midwife can provide the form (FW8) at your booking or scan appointment.
- Check your maternity pay and leave entitlement. Whether you're employed, self-employed, or not currently working, it's worth understanding what you're entitled to well ahead of time.
- Start thinking about a birth plan. It's early, but jotting down initial thoughts and preferences can make later conversations with your midwife easier.
- Look into antenatal classes. NHS and popular private classes (such as NCT or hypnobirthing courses) often book up, so researching and reserving a place now is sensible even if the class itself is months away.
Telling people and celebrating
- Consider announcing your pregnancy, if you'd like to — many people choose the 12-week mark because of the significant drop in miscarriage risk after this point, though there's no rule about timing.
- Take a moment to acknowledge the milestone. Reaching 12 weeks is genuinely significant, whatever the rest of your pregnancy looks like from here.
Frequently Asked Questions
What should I do at 12 weeks pregnant?
Key tasks include attending your 12-week scan, applying for your maternity exemption certificate, checking your maternity pay entitlement, and starting to think about antenatal classes and a birth plan. Many people also use this week to consider announcing their pregnancy.
When should I apply for my maternity exemption certificate?
You can apply as soon as you're pregnant, but many people do this around their booking or 12-week scan appointment when a midwife or GP can sign the form. It's worth doing sooner rather than later, as it can take a few weeks to arrive and covers free prescriptions and dental care.
Is nub theory accurate at 12 weeks?
Nub theory is a popular but non-diagnostic method based on the angle of a structure seen on the dating scan — it's best treated as a fun guessing game rather than a reliable prediction, as amateur attempts are no more accurate than chance. If you want a confirmed answer, the anomaly scan at around 18–21 weeks or NIPT blood tests are far more reliable.
