When your OB first tells you your due date, it feels like such a sacred number. You roll it over and over in your mind, and you proudly recite it when inquisitive friends, family members, and coworkers ask you when you're due. Yet, in reality, your baby could just as easily be born two weeks before or after that date. My daughter was born in a different month than her due date predicted. If you suspect your date might be wrong, here are some signs you due date is off, so you and your OB can make a game plan.
It may seem weird that a date assigned by a medical professional could be little more than a "guesstimate" but that's kind of what it is. In fact, only 5 percent of babies are born on their actual due date, according to Parents.
What's more, the method used to calculate due dates hasn't changed since the beginning of the 19th century, according to New York Magazine. You would think that with all the technological advances in fertility and fetal medicine, that due dates might have also gotten a boost, but nope, doctors still use something called the Naegele rule, which is when, "you take the first day of a woman’s last menstrual period, add a year, subtract three months, and add seven days," explained the New York Magazine article.
With calculations like that, you can see why due dates aren't exactly an exact science. But if you're looking for more clarity, here are five indicators that you might deliver earlier or later than your original due date suggests.
