Every Pregnancy is Unique

Gone are the days when all pregnancies were assumed to follow the same growth trajectory.

Traditional due date calculators and healthcare professionals often base their predictions on the baby’s size. However, numerous factors influence the length of a pregnancy.

Our state-of-the-art pregnancy prediction models offer personalized insight into the most probable day your child will arrive.

Some common FAQs

Read more questions and answers in FAQ.

Do I need an estimated due date from an ultrasound examination?

No. Our Early Forecast takes into account when you had your last period and is not dependent on you having had an ultrasound examination.

However, this is not our best prediction model but it is still better suited for you than the prediction you can make using the pregnancy wheel or standard due date calculators.
