MFM mums share their stories plus expert sonographers explain why it happens and what to do if you're told your due dates are wrong. By Rachel Mostyn. Original date given was 18 December but at the scan it was moved to 31 Dec. Unless you have an early pregnancy scan most of you will be given your estimated due date at the week scan. Of course you have probably already used an online due date calculator. Weird huh? But this will only give you a rough idea. This is especially true if you have an irregular cycle or have been on the Pill for example. Experts say that the scan date can sometimes come out as less pregnant than suggested by your LMP. But then again with my first baby I was spot on with dates, he always measured big and he was a week overdue… these babies like to be tricky!

Accuracy of Transvaginal Ultrasound for Dating Pregnancy

The timing of certain tests, the monitoring of the baby's growth, and the correct diagnosis of premature labor, or being truly "overdue," postdates , as well as many other situations that arise in the course of a typical pregnancy, all depend on a correct determination of the EDC for appropriate management. In the past, the EDC was calculated by using Naegele's Rule, which determined the date by subtracting 3 months from the 1st day of the last period and then adding 7 days. In fact, when a woman who has very regular, "textbook" 28 day cycles presents for prenatal care, this often turns out to be the correct EDC more often than not. Other information used to calculate the gestational age, or the number of weeks and days from the first day of the last menstrual period LMP , includes the size of the uterus on pelvic bimanual examination. However, it is extremely common to encounter patients who have irregular or infrequent menstrual cycles, or have fibroid tumors that cause their uterus to feel enlarged on pelvic exam, or who conceive shortly after a pregnancy ends without ever actually having had a period after the last pregnancy , or who got pregnant while taking birth control pills, and these situations often render the above methods useless and misleading when trying to figure out a reliable EDC. This is where our wonderful ultrasound machines can make a crucial difference. With today's modern equipment, we can obtain very reliable images and measurements of even very early pregnancies, sometimes even seeing a heartbeat as early as weeks!

Author information: To compare last menstrual period and ultrasonography in predicting delivery date. We used ultrasound to scan 17, nonselected singleton pregnancies at completed weeks. The last menstrual period LMP was considered certain in 13, and uncertain in cases. The duration of pregnancy from the scan to the day of spontaneous delivery was predicted by crown-rump length, biparietal diameter BPD , and femur length FL using linear regression models, and the results were compared with estimates based on LMP.
