You may have a earlier scan, if you are experiencing pain or bleeding for example or unsure of LMP dates. Transabdominal ultrasound TAU and also the transvaginal ultrasound TVU are valuable diagnostic tools in obstetrics and gynecology. Transabdominal ultrasound will provide a panoramic view of the abdomen and pelvis and is noninvasive, whereas transvaginal ultrasound provides a more limited pelvic view and requires insertion of a probe into the vagina. Transabdominal ultrasound cannot reliably diagnose pregnancies that are less than 6 weeks gestation.

References “The technology of prenatal diagnosis is usually presented to us as a solution, but it brings with it problems of its own If you’ve already read it, you may want to skip ahead. All pregnant women in our technology-happy modern society face confusing choices about prenatal testing, its advantages and disadvantages, and its appropriateness for them.
Large pregnant women face even more confusion, since prenatal testing can be slightly harder in this population, and the results can be more confusing.
HCG Levels for normal Pregnancy. The quantitative maternal serum beta HCG peaks at approximately 10 weeks and then reduces. 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 smae 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 Yolk Sac Only seen. The yolk sac will be visible before a clearly definable embryonic pole.

Normally the earliest technically satisfactory measurement will be the most accurate for dating purposes. Once the gestational age has been assigned, later measurements should be used to assess fetal size and should not normally be used to reassign gestational age.

I got back into the car without a word and kept driving. My oldest punched his sister. Just like I said we would. I had always just bagged them up, but they knew the bags would just go in my room and they would eventually get everything back. They learned to keep toys off the floor after that.

It is now recommended that all pregnant women have a dating scan in the first trimester – ideally at 10 to 13 weeks of pregnancy – to confirm your dates. This is especially important if you are going to have any screening tests for Down’s syndrome, as knowing the exact dates makes sure your result is .
Ultrasonic Fetal Measurement Standards If we assume a fetus is growing normally, biometric measurements are determined by gestational age, and we can estimate the gestational age and thus the due date. Conditions which alter fetal growth will make the estimates less reliable. Although many embryonic and fetal structures can be measured, only a few measurements are easy and repeatable enough for widespread use. The most common are: The first element to be measurable is the gestation sac of the early pregnancy.
The gestational sac is measured in three dimensions, and the average, the Mean Sac Diameter MSD used for estimating gestational age. The length of the embryo on the longest axis excluding the yolk sac constitutes the crown-rump length. The transverse width of the head at it’s widest. We measure from the the leading edge to leading edge of the bones, because this leading interface is most distinct.
Since the head is oval, the error induced by small errors in positioning is small, making for a repeatable, robust measure. The BPD best used after 12 weeks. The femur length is a repeatable measurement with accuracy similar to the BPD. It is effected by skeletal dysplasias, but since these are rare, it is a reliable measurement which confirms measurements of the head. It is best measured after 14 weeks.

To ultrasound or not to ultrasound? That is the question. For most pregnant mamas, ultrasounds are just a given. As a natural mama, we want to avoid as many interventions as possible during pregnancy and birth. Some studies also found that when women had an ultrasound for dating they were less likely to be induced for post-term pregnancy. However, if you have a practitioner like a midwife who is ok with continuing to closely monitor a post-term pregnancy, this may not be an issue for you.
