Understanding Extra Pregnancy Appointments: Your Guide to Additional NHS Care
DueDate.Baby Team
UK Pregnancy Experts
For many parents, the standard rhythm of NHS maternity care — the 12-week dating scan, the 20-week anomaly scan, and regular midwife check-ups — provides a reassuring and familiar framework. However, it is incredibly common for your care pathway to include extra appointments tailored specifically to you and your baby.
If your midwife or consultant suggests additional monitoring, it is rarely a cause for alarm. Instead, view these appointments as a premium layer of care, designed to provide deeper insight and genuine peace of mind as your pregnancy progresses. Your maternity team's goal is always the same as yours: a safe, well-supported journey to meeting your baby.
Here is a guide to the most common additional appointments you might encounter and exactly what they mean for your journey.
Quick Answer
Additional pregnancy appointments in the UK, such as growth scans, consultant-led obstetric care, or the oral glucose tolerance test (GTT), are proactive measures tailored to monitor your baby's progress. These extra checks provide deeper clinical insight and reassurance, ensuring a well-supported and safe pregnancy journey for both mother and baby.
What Is Consultant-Led Antenatal Care?
At your initial booking appointment, your midwife assesses your full medical history. If you have an existing health condition — such as high blood pressure, type 1 or type 2 diabetes, a history of pre-eclampsia, or a previous complex birth — you may be placed on a Consultant-Led Pathway alongside your standard midwifery care.
What happens: Alongside your regular community midwife appointments, you will visit the hospital antenatal clinic to see an obstetrician — a doctor specialising in pregnancy and birth. In many trusts, your named community midwife continues to be your primary point of contact, ensuring continuity of care throughout.
The focus: The consultant will review your progress, manage any necessary medications, and work with you to create a bespoke, safe birth plan that reflects both your clinical needs and your personal preferences. This is also a good time to ask about your options — including whether a midwife-led unit or home birth might still be possible within a consultant pathway.
A helpful tip: Keep your maternity notes with you at all times from your booking appointment onwards, and bring them to every single appointment — community, hospital, or otherwise.
Why Do I Need Extra Growth Scans?
While the standard NHS pathway includes two routine ultrasound scans, many parents are referred for additional ultrasounds during the second and third trimesters. These are often called Growth Scans or Growth and Doppler Scans, and they are a proactive measure rather than a sign that anything is wrong.
Why they happen: At every routine midwife appointment from around 28 weeks, your midwife will measure your fundal height — the distance from your pubic bone to the top of your uterus, in centimetres. This measurement is plotted on a customised growth chart specific to you. If the measurement falls slightly above or below the expected range, or if you have risk factors such as a higher BMI, a previous small or large baby, or a multiple pregnancy, a growth scan will be requested to check your baby's progress with greater precision.
What they measure: The sonographer takes careful measurements of your baby's head circumference, abdominal circumference, and femur (thigh bone) length to estimate their current weight. A Doppler ultrasound is also used to assess blood flow through the umbilical cord, ensuring your placenta is delivering oxygen and nutrients efficiently.
What to expect on the day: Growth scans are usually straightforward and feel similar to your 20-week anomaly scan. They typically take between 20 and 40 minutes. You are welcome to bring your birth partner, and many parents find them a wonderful opportunity to see their baby again in the later weeks of pregnancy.
What Happens During the Gestational Diabetes Glucose Tolerance Test (GTT)?
Between weeks 24 and 28, you may be invited to the hospital for a Gestational Diabetes screening, known formally as the Oral Glucose Tolerance Test (GTT). This is a standard and widely offered test — not a sign that something is wrong.
Why it happens: The GTT is routinely offered if you have certain risk factors for gestational diabetes, including a family history of type 2 diabetes, a previous baby weighing over 4.5kg, a BMI over 30, or if you are of South Asian, Black Caribbean, or Middle Eastern ethnic background, where gestational diabetes is statistically more common.
What to expect: You will be asked to fast (nothing to eat or drink except water) from midnight the night before. On arrival, a baseline blood sample is taken. You will then be given a measured glucose drink and asked to rest quietly — no walking around or eating — for two hours, after which a second blood sample is taken. This compares how efficiently your body processes sugar and whether insulin levels are responding as expected.
Practical tips for the day:
- Wear comfortable clothing with easy access to your inner arm for the blood draw.
- Bring a book, podcast, or something to keep you occupied during the two-hour wait.
- You can bring your birth partner to sit with you.
- Results are usually available within a few days via your midwife or maternity team.
If gestational diabetes is confirmed, your midwife will refer you to a specialist diabetes team. Most cases are managed very effectively through dietary adjustments, and your care team will support you every step of the way.
Why Might I Be Referred for Blood Pressure or Anaesthetic Reviews?
For some parents, pregnancy brings changes in blood pressure or reveals pre-existing considerations that warrant specialist input. These additional reviews are a sign that your team is taking thorough, individualised care of you — not that your pregnancy is in danger.
Hypertension & Cardiology Clinics: Your midwife will check your blood pressure at every appointment. If readings are consistently raised, or if you develop symptoms such as severe headaches, visual disturbances, or swelling in your face and hands, your team will want to rule out pre-eclampsia — a serious but manageable condition that the NHS monitors for closely. You may be referred to a hypertension clinic or day assessment unit for closer observation. In most cases, blood pressure is managed safely with pregnancy-compatible medication and lifestyle guidance.
Anaesthetic Consultation: An appointment with an obstetric anaesthetist is commonly offered if you have a higher BMI, scoliosis, previous spinal surgery, or complex medical conditions. Far from being alarming, this is a calm, conversational meeting — usually lasting around 30 minutes — to discuss your pain relief options for labour well in advance. It is the ideal time to ask questions about epidurals, spinal blocks, and what to expect if a caesarean section becomes necessary.
What Extra Monitoring Happens in the Final Weeks of Pregnancy?
From around 36 weeks, midwife appointments become more frequent for all parents — typically weekly or fortnightly. However, if you have been receiving consultant-led or enhanced care, your monitoring in the final stretch may include additional elements:
- Cardiotocography (CTG): A monitor placed on your bump to measure your baby's heart rate and any uterine activity. Often used if movements have felt reduced or if you have any risk factors.
- Biophysical Profile (BPP): A detailed ultrasound that observes your baby's breathing movements, body movements, muscle tone, and amniotic fluid levels, giving a comprehensive snapshot of their wellbeing.
- Amniotic Fluid Assessment: Checks that the volume of fluid surrounding your baby remains within the healthy range.
If any of these assessments raises a concern, your team will act promptly. In most cases, everything is reassuringly normal — and these checks give both you and your care team the confidence to proceed.
Frequently Asked Questions
Why has my midwife referred me for extra scans when my pregnancy seems normal?
Referrals for growth scans are often triggered by fundal height measurements that are slightly outside the expected range on your customised growth chart — not because your baby is definitely too large or too small. The scan is there to get a precise picture. In the majority of cases, the scan confirms that everything is progressing well.
Will extra appointments affect where I can give birth?
Not necessarily, though it does depend on the reason for additional monitoring. Many parents who receive extra scans or GTT screening go on to have straightforward births at a midwife-led unit or at home. Your consultant or midwife will discuss your safest options based on the full picture of your pregnancy.
Is the glucose tolerance test (GTT) compulsory?
No NHS test is compulsory — all screening is offered, not required. Your midwife should explain the purpose and process of any test, and you have the right to decline. However, most parents choose to have the GTT because identifying gestational diabetes early allows it to be managed safely, which protects both you and your baby.
What should I bring to a consultant appointment?
Always bring your maternity notes, a list of any questions you've prepared, your current medications (or a written list of them), and your birth partner if you'd like support. It helps to write questions down beforehand — consultant appointments can feel fast-paced, and it's easy to forget things you wanted to ask.
Can I still use my preferred birth plan if I'm on a consultant pathway?
Absolutely. A consultant pathway does not override your preferences — it adds clinical oversight to them. Your birth plan is still yours, and your midwife and consultant will work with you to honour as many of your choices as safely possible.
