Just found out you’re pregnant? Work out your baby’s due date with the Pregnacare Pregnancy Due Date Calculator.  

How Does The Due Date Calculator Work? 

To find out your pregnancy due date, simply enter the first date of your last menstrual cycle. 

How Is The Due Date Calculated? 

Generally, most women ovulate about 2 weeks after the first day of their period and will conceive shortly after. On average pregnancy lasts anywhere between 37 and 42 weeks, the Pregnacare Due Date Calculator will use this information to generate an estimated due date.  

Despite every care being taken to ensure the accuracy of this calculator the information contained in this tool is neither designed nor intended to serve as medical advice. We advise consulting your GP,midwife or healthcare professional if you have any concerns.   

How Accurate Is The Due Date Calculator? 

No one can say for certain when your baby will arrive, in fact, a very small percentage of babies are actually born on their due date. However, it is likely that your baby will be born in the few weeks either side of your estimated date. Knowing the rough date will help you prepare for the labour and birth in good time.  

Can My Due Date Change? 

Yes, your due date can change. Your doctor may change your due date for a number of reasons as your pregnancy develops, for example, the top of your uterus may be measuring differently than expected based on your predicted due date.
