Are you sure that you want to delete this answer? Yes Sorry, something has gone wrong. I had a horrible experience with my dates being wrong in my 3rd pregnancy. The doctor gave me another ultrasound because I was measuring a bit small for how far along I was. I was freaked out, to say the least. Then the doctor ordered a fetal biophysical profile because of the discrepancy in the dates.
A week later I had it done. I couldn’t stop crying. I had a positive pregnancy test in late Feb. By my math that’s 11 months I went and had that done and during the last few minutes of the non-stress test, I started having one contraction after another and they wouldn’t let me leave – so I was wheeled around the corner and put into a hospital bed to wait. The amnio came back that her lungs were almost mature and so they gave me a steroid to speed development of her lungs that day and the next day they inserted Cervadil to dilate my cervix.

Click here for additional information. I want to know if I should trust the accuracy on an ultrasound to date a pregnancy. Of all of these uses, dating the pregnancy is the most common reason to use ultrasound, particularly when the expectant mother cannot remember the date of her last period as in breast-feeding or irregular cycles.
When an ultrasound is performed, measurements of the head, abdomen, thigh, and amount of amniotic fluid are done. This creates error in that the baby will compute out to be further along than he or she really is. For instance, say you normally have eight and nine pound babies. Then your baby at 37 weeks will have bigger measurements than babies destined to weigh seven or eight pounds at birth. This may then indicate that your week baby is two weeks overdue!
Therefore, measurements taken later on, when babies begin to grow at different rates among pregnancies, yield increasingly inaccurate dating of pregnancy. Although the dating of pregnancy accuracy takes a dive, still ultrasound is indispensable for the other uses.

Find a Clinic Near You And Get Started Today near Home — Female Infertility — Miscarriage — Missed Miscarriage Missed Miscarriage A missed miscarriage , also known as a missed abortion or a silent miscarriage, occurs when a fetus dies, but the body does not recognize the pregnancy loss or expel the pregnancy tissue. As a result, the placenta may still continue to release hormones, so the woman may continue to experience signs of pregnancy.
A missed miscarriage is usually diagnosed during a routine checkup, where the doctor will fail to detect a heartbeat. A subsequent ultrasound will show an underdeveloped fetus. Signs of Missed Miscarriage A missed miscarriage is often known as a silent miscarriage because women generally do not have common miscarriage symptoms, such as vaginal bleeding, heavy cramping, or expulsion of fetal tissue.
With a missed miscarriage, the placenta may still release hormones, which can continue the signs of pregnancy for women.

It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests. Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.
Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis. This means that combined first trimester screening simply tells us if your risk is low or high. For example, it tells us whether your baby has a low risk of having trisomy 13, 18 or 21, or whether your baby has a high risk of having trisomy 13, 18 or This test gives us an indication of whether we should worry about your baby based on these results.
This means that combined first trimester screening will not give us a definitive answer.

Concerns Regarding Early Fetal Development
May 23, Seeing a positive pregnancy test can bring about a host of emotions, thoughts and questions. Your pregnancy is dated from the first day of your last menstrual cycle. This type of dating is based on averages, as many women ovulate about 14 days after the start of their last period, and expect a new period 14 days after ovulation.
However, the exact day of ovulation can vary from woman to woman and cycle to cycle. This means that this type of pregnancy dating is only an estimation. A transvaginal ultrasound an internal ultrasound can detect a heartbeat around 6 weeks of pregnancy.

Mean Sac Diameter measurement is used to determine gestational age before a Crown Rump length can be clearly measured. The average sac diameter is determined by measuring the length,width and height then dividing by 3. 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 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 Yolk Sac Only seen.

There are many reasons for having an ultrasound at this stage, but one of the most common is to screen for one of the congenital chromosomal abnormalities — Trisomy 21, otherwise known as Down Syndrome. This means that there is an extra chromosome — 21 contained in every cell of the body. People with Down Syndrome have physical and intellectual disabilities. Older women are more at risk of having a baby with Down Syndrome. When a woman is around 12 weeks pregnant her risk of having a baby with Down Syndrome can be fairly accurately assessed.
First trimester screening for Down Syndrome can be done with a blood test between 10 weeks and 13 weeks and 6 days. When a foetus has Down syndrome they tend to have more fluid at the base of their neck, in the region known as the nuchal fold area. This fluid can be measured in a test called nuchal translucency. This can be measured in an ultrasound done between 11 weeks and 13 weeks and 6 days. A foetus with Down Syndrome has a measurement which is thicker than in those who do not.
It is worth remembering though, that a larger than average nuchal fold measurement is not a guarantee that the baby will have chromosomal problems.
