Pregnancy (Due Date) Calculator
Professional Reference tools are designed for health professionals to use. They are written by UK doctors and based on research evidence, UK and European Guidelines, so you may find the language more technical than the condition leaflets.
This pregnancy due date calculator will give you a rough idea of when your baby should be born. If you know the date of the first day of your last menstrual period (LMP), or have already had your first ultrasound scan, you can use this tool. Please remember that the result will not necessarily be the day that your baby arrives. The actual date may be any time from 38 to 42 weeks in most pregnancies. If problems occur you may be advised that delivering your baby earlier is the safest option.
For advice on recognising signs that you are going into labour, or for information on some types of pain relief in labour, follow the links. We also have information on how your baby is monitored in labour.
