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.
If an early ultrasound gives you a due date that is more than 1. You may have simply conceived earlier or later than you thought you did which can happen if your cycle is at all irregular or if you remembered your last menstrual period date incorrectly.

Doing the maths. Due dates are calculated as 40 weeks from the first day of the last menstrual period LMP — or 38 weeks days from conception. Length of pregnancy is counted from the LMP, so four weeks after your LMP you would be counted as being four weeks pregnant even though you probably only conceived two weeks ago.
If you know when your LMP was, the easiest way to work out your due date is to go through the calendar counting forward in weeks till you get to forty weeks. Counting 38 weeks from conception is more accurate, if you know when it was, especially for women who do not have regular 28 day cycles. Remember, conception, when the sperm combines with the egg, can occur several days after sex.
Me! I was put back 6 days when I thought I was 9+3 & was told I was 8+4. Then at my 12 week scan where going by my new dates I was.
