Medical professionals and doctors can only answer so much. What they can do is monitor the health and development of the baby and make educated predictions about the future.
The most reliable thing is to now exactly when you ovulated, not an u/s. But earlier u/s is more accurate than later at w they are fairly accurate.
During the course of the pregnancy, every mother should have at least two scans. These help to ensure the pregnancy goes smoothly, and to identify any problems ahead of time. The dating scan is generally the first ultrasound that every mother-to-be will have. While many women will have a good idea of when they had their last menstrual period, another portion will be far less certain. This can be due to a number of factors, including whether the pregnancy was planned or not, and if the mother often has irregular periods.
The scan also gives a due date, which is sometimes a small range of dates due to a difference with your own dating attempt.
How accurate is my ‘due date’?
There are two types of pregnancies. Those that are planned and those that just happen. The pregnancies that are spontaneous will often make you wonder, when did all this happen? Apart from satiating your curiosity, it has other health-related implications. For instance, there are cases where doctors have unnecessarily induced labour because there is uncertainty about how old the foetus is.
This can result in premature birth.
When you are offered a dating scan and the sonographer gains a picture of the baby’s development, they can use this to accurately calculate the baby’s age.
Throughout my pregnancy , I’ve received two different due dates — one came from my very first ultrasound, when my baby was barely the size of a blueberry, the date that was then subsequently stamped on my record as “the” due date. But then there was a second date, the one that showed up on my next couple of ultrasound scans. This date was a few days earlier. It’s also the date that I prefer, not only because I’m now 38 weeks pregnant and ready to get this baby out, but because it matched the date I’d calculated on my own using information I looked up.
And how much does it really matter? After all, as many moms know, due dates are just educated guesses. Traditionally, estimated due dates are calculated by taking the start date of a woman’s last menstrual period and adding a year, subtracting three months and adding seven days, a method known as Naegele’s rule.

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?
