Your Pregnancy Journey
We provide a range of community services in Harrogate and the local area as well as across North Yorkshire and Leeds. At your initial booking appointment, you will be offered a range of important tests to screen for certain conditions that may affect your pregnancy. It is important for you to be aware that ultrasound scanning is a form of screening and is done to perform important checks on the health and development of your baby. The combined test involves a blood test and a nuchal translucency NT ultrasound scan in the first trimester of pregnancy, normally at 12 weeks.
At this stage of your pregnancy you will be starting your antenatal care and will be offered a dating scan around 12 weeks. At these appointments you will be given a range of information about your options during pregnancy. This information is to help you to make informed choices. The aim is to promote care, which is safe and personalised to you and your baby.
