How accurate is a dating scan at 9 weeks

Just curious how accurate those early dating scans are? I just can't wrap my head around the 12 day difference. I know due dates are just estimates but I wish they had a better idea of it as I don't think the 6th or the 18th is correct! I know my 1st dating scan was a week later than it is now Everything is so small at that stage so the measurement they do get is very iffy All of my scans have dated me correctly and my EDD has stayed the same throughout.

Depending on your unique pregnancy, your chosen healthcare professional may schedule an earlier ultrasound at nine weeks for a few different reasons.

If this is your first ultrasound, it will give you the opportunity to accurately determine your due date. Knowing how far along you are in your pregnancy is important. At some point between 11 and 13 weeks your healthcare professional will suggest conducting a Nuchal Translucency NT scan. This scan tests for Down syndrome and for accurate results, you need to know how far along you are.

If you have miscarried a previous pregnancy or you have experienced some level of vaginal bleeding over the last nine weeks, you may also be offered an ultrasound. This scan can confirm whether your pregnancy is progressing healthily. This ultrasound may be conducted vaginally or externally on your abdomen. Know that if your healthcare professional has officially referred you for an early scan Medicare will cover it.

Bring some tissues with you; this can be a very emotional moment. If your ultrasound shows that your baby is growing slowly, or has a lower than average heartbeat your chances of miscarrying are high. If you have been experiencing pain or vaginal bleeding, you might be somewhat prepared for this news. However, no matter how prepared you think you may be, hearing your miscarriage suspicions confirmed is likely to be a distressing experience.

9 Week Ultrasound

The purpose of this study was to determine the accuracy of sonographer predictions of fetal gender during routine ultrasounds. Primarily, the study sought to investigate the accuracy of predictions made in the first trimester, as requests from parents wanting to know the gender of their fetus at this early scan are becoming increasingly common. Second and third trimester fetuses were included in the study to confirm the accuracy of later predictions. In addition, the mother's decision to know the gender was recorded to determine the prevalence of women wanting prenatal predictions. A prospective, cross sectional study was conducted in a specialist private obstetric practice in the Illawarra, NSW. A total of fetuses across three trimesters were examined collectively by seven sonographers.

The gestational sac GS is the earliest sonographic finding in pregnancy. It will be difficult to see if the mother has a retroverted uterus or fibroids. The GS is an echogenic ring surrounding an anechoic centre. An ectopic pregnancy will appear the same but it will not be within the endometrial cavity. Gestational sac size should be determined by measuring the mean of three diameters. These differences rarely effect gestational age dating by more than a day or two. The following image is using a transvaginal approach the gestational sac can be seen during week The fetal pole grows at a rate of about 1 mm a day, starting at the 6th week of gestational age. Thus, a simple way to "date" an early pregnancy is to add the length of the fetus in mm to 6 weeks. Using this method, a fetal pole measuring 5 mm would have a gestational age of 6 weeks and 5 days.

Ultrasounds are one of the most exciting parts of a pregnancy—a first chance to see your unborn child. An ultrasound is a noninvasive procedure, performed vaginally or abdominally, that causes no pain to mom or baby. There is no standard timeline or number of ultrasounds recommended, so your ultrasound schedule will be determined by your specific needs and vision for your pregnancy.
