Our Due Date Calculator is here to help you estimate when your little one will be arriving. Most pregnancies last about 40 weeks, so you can get an idea of your due date by counting 40 weeks, or 280 days, from your last menstrual period (LMP). You can also subtract 3 months from the date your last period began, then add 7 days. Or instead of all the counting, enter the date of your LMP into the calculator above!
Once you enter the date of your last menstrual period, the calculator will tell you your estimated Conception Date (when you actually got pregnant) and your estimated Due Date.
Remember, these are just estimations based on a 28-day menstrual cycle. If your cycle is irregular then it will be more difficult to estimate your Due Date using dates alone. You’ll receive a much more accurate Estimated Due Date (EDD) when you have a scan.
If you can’t wait to find out your EDD, visit us in UltraScan where we perform Early Pregnancy Scans (or Dating Scans) from just 8 weeks.
