NHS antenatal appointments: your schedule from booking to birth
Antenatal care is the regular, structured support you receive from your midwife and obstetric team throughout pregnancy. These appointments are not merely administrative; each one serves a specific clinical purpose, whether that is checking your blood pressure, measuring how the baby is growing, or giving you time to ask questions and make informed decisions about your birth. The NHS organises this care differently depending on whether you are having your first baby or a subsequent one, and knowing the schedule in advance helps you prepare, plan around work and childcare, and make sure nothing gets missed. This guide sets out the full schedule, explains what happens at each appointment, and covers the tests and checks you can expect.
First pregnancy compared with subsequent pregnancies
The NHS recommends 10 antenatal appointments for a first pregnancy and 7 for subsequent pregnancies. The difference exists because people expecting their second or later child have already been through the process; some of the earlier check-ins that establish baseline measurements and introduce the care pathway are condensed or omitted. The schedule for a second or later pregnancy focuses on the appointments where clinical action is most likely, though your midwife can add extra visits at any point if there is a clinical reason. If this is your first pregnancy, the fuller schedule reflects the additional time needed to take a thorough medical and family history, establish care, and give you the opportunity to ask the many questions that naturally arise when navigating pregnancy for the first time.
The booking appointment: 8 to 12 weeks
The booking appointment is typically the first formal contact you have with your midwife, usually taking place between 8 and 12 weeks of pregnancy. It is longer than any subsequent appointment, sometimes lasting an hour or more, because a great deal of ground needs to be covered. Your midwife will take a detailed personal, obstetric and family health history to identify any factors that might affect how your pregnancy is managed. Blood pressure and weight are recorded, and blood samples are taken for a range of tests covering blood group and rhesus factor, anaemia, infections including syphilis and HIV, and immunity to conditions such as rubella.
The booking appointment is also the point at which you are offered screening for chromosomal conditions and given information about the 12-week scan. Your midwife will discuss your options around place of birth, infant feeding, and any lifestyle factors relevant to your pregnancy, including folic acid supplementation and vitamin D. Coming prepared with a list of any medications you take and, if you know it, your last menstrual period date will help the appointment run efficiently.
The 12-week dating and screening scan: 10 to 14 weeks
Between 10 and 14 weeks you will be offered the dating scan, which is the first ultrasound of the pregnancy. It gives a more accurate estimate of gestational age than the last menstrual period alone, and it produces the expected due date that will be used for the rest of your care. If you are expecting more than one baby, this scan is when that is confirmed and chorionicity (how the babies share or do not share a placenta) is assessed.
At around the same time, you are offered the combined screening blood test. This test measures levels of two pregnancy hormones in your blood and is considered alongside the nuchal translucency measurement taken during the scan to give a risk estimate for conditions including Down's syndrome, Edwards' syndrome and Patau's syndrome. The result is expressed as a probability rather than a diagnosis. If the result comes back as higher chance, you will be offered further testing such as non-invasive prenatal testing (NIPT) or diagnostic procedures to obtain a definitive answer.
16 weeks: reviewing results and baseline checks
The 16-week appointment is a review and check-in rather than a major procedural visit. Your midwife will go through the results of the booking blood tests and combined screening, giving you the chance to ask questions about anything that came back or to discuss next steps if a result requires follow-up. Blood pressure and urine are checked at this point, establishing a baseline that will be compared at every subsequent visit. This is a good opportunity to discuss any symptoms you have been experiencing and to ask about what to expect over the coming weeks, including the anomaly scan.
The 20-week anomaly scan: 18 to 21 weeks
The anomaly scan, offered between 18 and 21 weeks, is a detailed ultrasound examination of the baby's anatomy. The sonographer checks the baby's brain, spine, heart, kidneys, abdomen and limbs, looking for a range of structural conditions. This is a screening scan, meaning it looks for signs that something may need further investigation; it is not diagnostic in itself, and not all conditions can be detected by ultrasound. The position of the placenta is also noted, which is relevant later in pregnancy if it lies low and may be covering the cervix.
Most people find this scan reassuring, but it is worth being aware that it can occasionally identify something that requires further discussion or referral. The sonographer and your midwife team will guide you through any findings and the options available to you.
25 weeks: blood pressure, urine and fundal height
The 25-week appointment is included in the schedule for first pregnancies. By this point in pregnancy, fundal height measurement, which is the measurement from the top of the pubic bone to the top of the uterus using a tape measure, begins to be recorded. In centimetres, the measurement should broadly correspond to gestational age from around 24 weeks onward. Any significant deviation from the expected range may prompt a referral for a growth scan to look more closely at how the baby is developing. Blood pressure and a urine dipstick test for protein are also carried out, continuing the pattern of monitoring for conditions such as pre-eclampsia.
28 weeks: blood tests and more
The 28-week appointment is one of the more comprehensive mid-pregnancy visits. Blood pressure, urine and fundal height are all checked, and blood tests are taken to assess for anaemia through a full blood count. This is an important point in the pregnancy for haematological monitoring because iron needs increase significantly in the second half of pregnancy and anaemia, if present, benefits from early treatment.
Women who are rhesus-negative are offered an anti-D injection at around this appointment. Rhesus factor is relevant because if a rhesus-negative mother carries a rhesus-positive baby, some fetal blood can cross into the maternal circulation during pregnancy and sensitise the immune system. Anti-D prophylaxis prevents sensitisation and protects future pregnancies. If you are unsure of your rhesus status, it will have been identified in your booking bloods and recorded in your maternity notes.
31 weeks and 34 weeks
The 31-week appointment, which is in the first-pregnancy schedule, includes the routine blood pressure, urine and fundal height checks, along with a review of the 28-week blood test results. It is also a good opportunity to ask questions about the remainder of pregnancy, what signs of labour to look out for, and practical matters such as birth preferences.
At 34 weeks, rhesus-negative women who have not already received anti-D may be offered a second dose. Fundal height, blood pressure and urine continue to be checked. Discussions about birth options and the birth plan typically begin in earnest around this time, covering preferences around pain relief, who will be present, and what matters most to you about the birth experience. There are no right or wrong answers; the aim of these conversations is to ensure that your wishes are known and, where possible, supported.
36, 38, 40 and 41 weeks: preparing for birth
The 36-week appointment includes an assessment of the baby's position. From around this stage of pregnancy, your midwife will feel your abdomen to determine whether the baby is head-down (cephalic), breech, or in another position. If the baby is not head-down, you may be referred to a consultant to discuss options, which can include an external cephalic version (ECV), a procedure that uses gentle pressure on the abdomen to encourage the baby to turn. The 36-week visit is also a good time to discuss your birth plan in detail and to make sure you know what to do when labour begins, including when to go to your chosen place of birth and what to bring with you.
The 38-week appointment continues the routine checks and gives you a further opportunity to raise questions. By 40 weeks, if you have not gone into labour, the appointment focuses on a discussion about your options. Post-dates pregnancies carry a slightly increased risk of certain complications, and your midwife or doctor will explain the evidence around waiting for labour to start naturally compared with induction. If you reach 41 weeks, induction will be offered and the risks and benefits of induction compared with expectant management will be discussed so you can make an informed decision.
What happens at most appointments
While the content of each appointment varies, three checks appear at virtually every visit from the booking appointment onward: blood pressure, a urine dipstick test and, from around 24 weeks, fundal height measurement. Blood pressure monitoring is important throughout pregnancy because hypertension is a key feature of pre-eclampsia, which can develop without causing obvious symptoms. The urine dipstick checks for protein, which when combined with high blood pressure can indicate pre-eclampsia, as well as for signs of urinary tract infection. Fundal height gives a simple, non-invasive indication of fetal growth over time. Taken together across multiple appointments, these three measurements build a picture of how both the pregnancy and the baby are progressing.
Between appointments
Your midwife is available to you between scheduled appointments and you should never feel that you need to wait for the next visit if something concerns you. Any of the following warrants prompt contact with your midwife or maternity unit, without waiting: reduced fetal movement, any vaginal bleeding, a gush or trickle of fluid that might be your waters breaking, severe headache that does not ease with paracetamol, pain just below your ribs, visual disturbance, or significant swelling of the face, hands or feet. None of these should be observed and monitored at home; they all require professional assessment.
Frequently asked questions
How many antenatal appointments will I have in a first pregnancy?
The NHS recommends 10 antenatal appointments for a first pregnancy and 7 for subsequent pregnancies. These cover scans, blood tests, blood pressure and urine checks, and discussions about birth plans and infant feeding.
What happens at the 28-week appointment?
At 28 weeks you will have blood pressure and urine checks and a fundal height measurement. Blood tests are taken to check for anaemia, and rhesus-negative women are offered an anti-D injection.
What is fundal height measurement?
Fundal height is measured from the top of the pubic bone to the top of the uterus using a tape measure. In centimetres, it should roughly correspond to gestational age from about 24 weeks onward. If measurement differs significantly from expected, a growth scan may be arranged.
Can I contact my midwife between appointments?
Yes. Your midwife is available between scheduled appointments and you should not wait until your next appointment if you have concerns about reduced fetal movement, bleeding, significant pain, or any other worrying symptom.
