How to Calculate Your Due Date

The thing is, because the date carries such meaning to us, we hang everything on it, and rightly so. We start planning, things like…. Yes, I kid you not!

Every pregnant woman wants to know her due date. But a due date calculated from last menstrual period with a due date calculator often doesn’t match the due date that is estimated by ultrasound also known as a sonogram. During an ultrasound, a technician spreads a warm gel over the lower part of the abdomen, and then presses a tool called a transducer against the belly to examine the fetus using sound waves.

An image of the fetus appears on an accompanying computer screen. While looking at this image, the technician takes some standard measurements from different angles and listens for a heartbeat. Sonograms are risk-free, and seeing your baby will likely be an enjoyable experience. Naturally, one of the most common questions asked about ultrasound is: Just how accurate are due dates predicted by ultrasound? Evidence suggests that, in the first 20 weeks of pregnancy , the first ultrasound may be the most accurate tool for calculating a fetus’s gestational ages.

Due dates predicted with early ultrasound have a margin of error of roughly 1. Doctors will usually keep the original due date the one generated by the date of the last menstrual period if the ultrasound due date is within that margin of error. If you can’t remember the date of your last menstrual period date, an early ultrasound can give you a fairly reliable due date. Ultrasound dating is also helpful if your menstrual cycles are irregular.
