Every baby is unique, and your little one might arrive outside of this timeframe. Remember, your due date is only an estimate. With our Pregnancy Due Date Calculator, input your preferred method and dates, then the calculations are made for you. In the same process as the last menstrual period method, 266 days are counted from the conception date to get an estimated due date. If you choose this calculation method, our Due Date Calculator will quickly work out your estimated due date, using both the date of your last period and the length of your regular cycle (tailoring it accordingly for longer, shorter, and average cycle lengths).Ĭonception date: If you know exactly when your baby was conceived, you can use this date to make a prediction of how far along you are. This method of predicting your due date is to count 40 weeks, or 280 days, from the first day of your last menstrual period - a common method used by a healthcare provider to estimate your due date if you have not yet had an ultrasound. Luckily, our Due Date Calculator can help. Unless you can pinpoint exactly what point of your ovulation cycle you were in at the time of fertilization, it’s difficult to know how far along you are and what date you’ll meet your baby. That means that simply estimating nine months from the day you take a pregnancy test isn’t going to calculate your due date, and, even so, factoring in a few weeks here and there for ovulation won’t either. Many won’t be aware of their pregnancy until their first missed period, and by that time they could be up to five weeks in. Most expectant mothers don’t realize that both menstrual and ovulation periods count as the first two weeks of pregnancy. The first day of your last period: While it’s true that most pregnancies last 40 weeks, there are other factors at play which will determine your due date. With our Pregnancy Due Date Calculator, we based our estimations on either the date of your last period or your conception date. Your due date can be estimated in several ways: the date of your last period, conception date, IVF-transfer date, or using an early ultrasound. Which calculation method should I choose?
