This means you can sometimes determine when you conceived based on your ovulation cycles — simply determine when your last menstrual period was and add approximately two weeks. In other words, calculating conception based only on your body cycles can be difficult. Another way to learn your conception date is to try to determine the last time you had sexual intercourse.

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.

Luckily, there are ways to figure out your due date when you can’t remember the first Some pregnancy wheels may allow you to enter the date of conception.

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.

How accurate is your baby’s due date? What to know about when you’ll go into labor

At seven weeks pregnant, your baby is about the size of a blueberry! Since most women don’t know the exact date of conception, the standard method for charting a pregnancy is by counting forward from the first day of your last menstrual period LMP. This method assumes that you ovulate 14 days after your period begins and that you’ll remember the day your period started! These results give health care providers—and you—a ballpark estimate for your baby’s due date.

For more accurate pregnancy dating, health care providers can request an ultrasound. Careful measurements taken in the first trimester are even more accurate at predicting an embryo’s age than ultrasounds performed later in pregnancy.
