The only really reliable person who can determine the exact date of your baby’s arrival is – you guessed it – your baby. Every other prediction is only an estimate, based on a variety of different factors.

To determine an approximation of your due date, your health care provider will ask you for the first day of your last menstrual period, and then count 280 days from that date, which is 40 weeks or 9 months.

If you can’t remember the first day of your last period, your due date can still be determined with an ultrasound when the technician takes various measurements of the baby. Since most babies grow at the same rate until 13 weeks, an ultrasound can be an accurate predictor of your due date up until that point. However, after 13 weeks of pregnancy, there are more factors at play that could influence a baby’s growth, making your baby’s age more difficult to gauge.

A due date isn’t written in stone. If your due date arrives, don’t feel like you have to jump on the induction train. There are numerous complications that may arise from inductions, not only for your baby, but for yourself as well.

A due date is only an estimate, and if you go a little over, don’t worry! Take the extra time to prepare for the baby and enjoy the last stages of pregnancy.
