Have you recently found out that you are pregnant? Congratulations! Our pregnancy due date calculator will help to give you an idea of when you might expect your baby.
You’re about to embark on an amazing journey. And one of the first things you’ll want to know is when your baby might be due.
Your due date is often referred to as your ‘estimated date of delivery (EDD)‘, every pregnancy is different and this is just an estimate.
How do I calculate when my baby is due?
It’s really impossible to say exactly when your baby might be born.
But a pregnancy due date calculator will help to give you a pretty good idea, certainly within a few weeks, so that you can start to prepare for the big day!
Of course, even with a very accurate due date, baby may arrive earlier or later than the date. But knowing roughly when your baby is due means you can start planning your parental leave, baby scans and begin thinking about pre and post-natal health and nutrition, etc.
Let’s give it a go now…
