Our Early Forecast

This forecast is for you who have not yet had an ultrasound examination. This is the most personal forecast you can make until you have had an ultrasound, after that Our Best Forecast is most reliable.

Unlike the midwife's pregnancy wheel and regular "due date calculators", Our Early Forecast takes into account individual factors that apply to you and your child.

Thanks to Pregspect’s forecast, I was mentally prepared to pass my due date. Many of my friends found every day after passing their due date to be long and tedious, but I didn’t feel that way.
