      How is my pregnancy due date calculated?

      Unless you’ve been keeping track of when you ovulate, it’s impossible to work out when you conceived, and therefore, when your baby will arrive. That’s why we use the date of your last period and the average length of your menstruation cycle to calculate your due date.

      Will my due date change when I have a scan?

      You’ll get a more accurate due date once you have your dating scan. While it’s unlikely your baby will arrive on this exact date, most babies arrive within a week of their due date.

      Calculating Your Due Date

      Powered by Nutricia

      Ovulation and conception usually occur about two weeks after the first day of your period, and the average pregnancy lasts between 37 weeks and 42 weeks. Using this information, along with the average length of your menstruation cycle, we are able to calculate your estimated due date.
