Many women and their families are concerned about how the strain on the NHS and the advice to socially distance themselves will affect their care during pregnancy. Whereas it is not possible to predict what impact COVID will have on staffing and provision on a national level and what measures individual Trusts will take to work through this crisis, we do know that care for pregnant women will remain a priority. The antenatal care-pathway the schedule of appointments and content during pregnancy is very similar throughout the United Kingdom and the timing of most routine appointments during the first half, or a little more, of your pregnancy can be relatively flexible without compromising your care.
The following overview aims to offer you some information and reassurance about possible changes to your antenatal care. This is typically your first contact with your community midwife and it can take place any time after your 5 th week of pregnancy. Having your booking appointment later than 10 week gestation could affect your screening choices , as certain tests are time-specific. So, if you find that your booking appointment has been cancelled or postponed, or you have to self-isolate, you are likely to have a wide margin of flexibility to rearrange it.
If you are already over 11 weeks pregnant, however, an inevitable re-scheduling of your booking appointment may mean that your dating scan will occur later, possibly affecting your choices to have screening for certain chromosomal syndromes. Being seen after your 10th week of pregnancy, may also mean you miss out on the optimal timing to have screening for certain inherited blood disorders and certain infectious diseases.
However, although early detection of these is ideal, you can still be screened for them at any time during your pregnancy. Many Trusts are using telephone or online services instead of face-to-face encounters for those appointments that allow it. It may be that part of your booking appointment can be completed this way, whilst tests and observations are performed at a different time.
NHS and private ultrasound scans during pregnancy
The main purpose of a dating scan is to check the stage of pregnancy and therefore when the baby is due. Measuring the baby can be more accurate than dating by the last menstrual period. It is also an opportunity to check the baby is alive and developing as expected, and check for twins. This scan may also be part of your screening test for Down’s syndrome nuchal translucency scan.
Occasionally, if the baby is in an awkward position, an internal scan may be carried out, using a vaginal probe.

It is common to be given a single ‘estimated due date’ EDD which corresponds the point at which it is estimated that your pregnancy will have lasted 40 weeks. It may be more helpful to be prepared for you baby arrive some time after 37 weeks, and to focus on 42 weeks as the time by which you have a good chance of having given birth. Many women with longer pregnancies find that everyone is asking whether they have had their baby yet, and that health care workers start to suggest inducing labour.
For some women this will be the right decision, but it is important to know that this is your decision to make. Charting temperature, monitoring mucus, using ovulation test kits and knowing times when you could have conceived, or having conceived by IVF may mean you have your own information about when you became pregnant. There is a tendency for midwives and doctors to talk as though the EDD written in your maternity notes is something definite, rather than an estimate which may or may not be accurate.
In that case, if the EDD is later than it should be that could mean that the birth is delayed unnecessarily. This suggests that in general ultrasound dating is more accurate in predicting the birth date than counting from the last monthly period 1,2 but it is still only an estimate and may not always be accurate.
A recent study 3 of women who conceived by IVF and therefore knew when their egg was fertilised, found that the routine ultrasound dating scan consistently put their estimated birth date earlier than it should have been by an average of 3 days. In any case, ultrasound does not give a very accurate prediction of the actual birth date.
Dating from ultrasound scans done later than about 20 weeks is increasingly less accurate. If a later scan predicts a date that is too early, this would make it appear that the pregnancy is lasting beyond 42 weeks, when in fact this is not the case. For this reason the American College of Obstetricians and Gynecologists has recommended that that due dates should only be changed in the third trimester in very rare circumstances. If the date in your notes has been changed because of a late scan, you might want to question how accurate that is likely to be.
