Obstetric dating and assessment
Pregnant women should be offered an early ultrasound scan between 10 weeks 0 days and 13 weeks 6 days to determine gestational age and to detect multiple pregnancies.This will ensure consistency of gestational age assessment and reduce the incidence of induction of labour for prolonged pregnancy.This information should include where they will be seen and who will undertake their care. At each antenatal appointment, healthcare professionals should offer consistent information and clear explanations, and should provide pregnant women with an opportunity to discuss issues and ask questions. Pregnant women should be informed about the purpose of any test before it is performed.
Prescription medicines should be used as little as possible during pregnancy and should be limited to circumstances in which the benefit outweighs the risk.
Information should be given in a form that is easy to understand and accessible to pregnant women with additional needs, such as physical, sensory or learning disabilities, and to pregnant women who do not speak or read English.
 Pregnant women should be offered information based on the current available evidence together with support to enable them to make informed decisions about their care.
This will help healthcare professionals to provide the recommended evidence‑based care to pregnant women.
A schedule of antenatal appointments should be determined by the function of the appointments.
