UK Pregnancy Experts
For many people, the first weeks after a positive test are a strange mix of excitement, anxiety, and uncertainty — particularly around the practical question of what you're actually supposed to do next. The good news is that the UK's maternity system is well-structured, and once you know how to enter it, it moves smoothly. This guide walks you through the key steps of the first 12 weeks: registering for care, what to expect at your booking appointment, how to navigate the NHS and private options, and what happens at your dating scan.
Quick Answer
Navigating the first trimester in the UK involves registering for care directly with a midwife via NHS self-referral, attending your booking appointment between weeks 8 and 10, deciding between NHS, private, or hybrid care, and attending the 12-week dating scan (between weeks 10 and 14) to confirm your estimated due date.
How Do I Register With a Midwife in the UK?
The first thing to do after a positive test is register for maternity care — and you don't need to go through your GP to do it. Most areas in England now use self-referral, meaning you can contact your local maternity unit directly.
The easiest way to find your local pathway is to search for your NHS Trust name and "maternity self-referral." Most Trust websites have a short online form where you enter your contact details and the date of your last period. Some areas use digital platforms such as Badger Notes, which becomes your ongoing digital maternity record once you register — you'll use it to view appointment notes, test results, and your care plan throughout the pregnancy.
If self-referral isn't available in your area, a GP appointment is still a perfectly valid route. Your GP will write a referral letter to your local maternity unit, and the process continues from there.
When to register: As soon as you have a positive test. You won't be seen immediately, but registering early ensures your booking appointment — your first formal midwife appointment — falls at the right time, ideally between weeks 8 and 10.
What Happens at My First Midwife Booking Appointment?
The booking appointment is your first real point of contact with the maternity system, and it's more involved than a routine check-up. Expect it to last around an hour. Its purpose is less about examining you physically and more about the midwife building a complete picture of your health, your circumstances, and what kind of care you'll need.
The midwife will go through your full medical history — including any previous pregnancies, existing conditions, and any mental health history. This last point is worth knowing in advance: they will ask directly about anxiety, depression, and previous mental health treatment. This isn't intrusive; it's so that additional support can be offered proactively if needed. Answer honestly.
They'll also discuss your lifestyle, your work situation if relevant, and the screening tests available to you during pregnancy, so you can make informed decisions rather than being asked to consent to things on the spot at the scan.
What to bring:
- Your NHS number (on any previous NHS correspondence, or find it via the NHS app)
- Details of any regular medication
- The date of your last period
- A list of any questions you want to ask — you'll have time, and the midwife will expect them
Your Maternity Exemption Certificate
One of the most valuable things to ask for at your booking appointment is the FW8 form, which entitles you to a Maternity Exemption Certificate. This is easy to overlook in the busyness of the appointment, but it's worth asking for specifically. It gives you:
- Free NHS prescriptions for the duration of your pregnancy and for 12 months after your baby's due date
- Free NHS dental treatment for the same period
Your midwife signs the form, you send it off, and the certificate arrives by post. It costs nothing and many people don't claim it simply because nobody told them to ask.
NHS or Private Care?
In the UK, comprehensive maternity care is available free through the NHS, and for the vast majority of people it provides excellent support throughout pregnancy and birth. Some people choose to supplement this with private care, or in some cases to go entirely private.
The most meaningful difference between the two isn't cost — it's continuity. On the NHS, you will typically see whichever midwife is available at each appointment, which means building a relationship with a single person is less common (though some areas offer dedicated caseload midwifery). With a private or independent midwife, you have one named person throughout: the same face at every appointment, at your birth, and in the days afterwards. Appointments are also considerably longer — often an hour versus the NHS's 15–20 minutes — and home visits are standard.
The hybrid approach is what many people settle on: staying with the NHS for primary care while paying privately for specific extras. The most common additions are private reassurance scans (particularly between weeks 6 and 10, before the NHS dating scan), and hiring a doula — a non-clinical birth partner who provides emotional support and continuity during labour, regardless of where you give birth.
If you're considering independent midwifery, it's worth knowing that costs vary significantly depending on your area and the level of care agreed. A full package covering pregnancy, birth, and postnatal care typically runs into several thousand pounds.
What Should I Expect at My 12-Week Dating Scan?
Despite the name, the dating scan can take place anywhere between weeks 10 and 14. It's the appointment most parents count down to — the first time you'll see the baby on screen — but it also serves two specific clinical purposes.
Arriving prepared: You'll be asked to come with a full bladder. This isn't uncomfortable for most people, but it does make a difference to image quality: a full bladder pushes the uterus upward, giving the sonographer a clearer view.
What happens: A cold gel is applied to your abdomen and a handheld probe is moved across the skin. The procedure is painless, though the sonographer may apply some pressure to get a better angle or encourage the baby to shift position.
The dating part: The sonographer measures the baby from the top of the head to the base of the spine — known as the crown-rump length (CRL). This is currently the most accurate method for calculating your Estimated Due Date (EDD). If the measurement suggests a different date from your last period, the scan date takes precedence — this is normal and simply reflects the natural variation in early development.
Screening: If you've consented in advance, the sonographer will also take a measurement of the fluid at the back of the baby's neck, known as the nuchal translucency (NT). This, combined with a blood test taken around the same time, forms the combined screening test — which assesses the statistical likelihood of chromosomal conditions including Down's syndrome, Edwards' syndrome, and Patau's syndrome. You'll receive results within a couple of weeks. A higher-chance result is not a diagnosis; it's an invitation to discuss further testing with your midwife.

It is a certificate that entitles you to free NHS prescriptions and free NHS dental treatment during your pregnancy and for 12 months after your due date. Ask your midwife for the FW8 form at your booking appointment to apply.
Is the 12-week dating scan always done exactly at 12 weeks?
