Objectives : 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.

Most pregnancies last around 40 weeks or 38 weeks from conception , so typically the best way to estimate your due date is to count 40 weeks, or days, from the first day of your last menstrual period LMP. Another way to do it is to subtract three months from the first day of your last period and add seven days. So if your last period started on April 11, you’d count back three months to January 11 and then add seven days, which means your due date would be January Calculating your due date based on the first day of your last period works well for women who have a relatively regular menstrual cycle.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
Dating scans are usually recommended if there is doubt about the validity of the last menstrual period. By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures.
Traditionally three factors are used to calculate the risk of trisomies: crown-rump length (must be 45 to 84 mm, gestation age 11 weeks 3 days to 13 weeks 6 days).
By around eleven weeks, your baby officially becomes a foetus from an embryo. Distinct facial features and genitalia are developing in your baby, and the eleven-week scan gives an exciting preview to the way your baby is growing inside you. The scan performed at eleven weeks is also medically significant for ruling out any anomalies, syndromes, or malformations. The first-trimester pregnancy scan is always very special as it gives a glimpse of the developing baby.
The week 11 scan gives you a sneak peek into how your baby looks, for the first time. It also is the earliest stage at which the doctor can pick up certain anomalies in the baby.

It may be more helpful to be prepared for you baby arrive some time after 37 weeks, and to focus on 42 weeks as the time by which you have a good chance of having given birth.

Charting temperature, monitoring mucus, using ovulation test kits and knowing times when you could have conceived, or having conceived by IVF may mean you have your own information about when you became pregnant.

The nuchal translucency NT refers to the pocket of fluid at the back of the fetal neck. The measurement of the nuchal translucency is part of the combined screening test for trisomy 21 and trisomy 18, called enhanced First Trimester Screen eFTS. An increased NT measurement increases the chance for other chromosome differences, additional genetic conditions, and can also be helpful to predict structural differences that might be more obvious later in pregnancy such as a heart defect.
At the time of the NT ultrasound, the sonographer or physician who does the scan can also accurately predict your due date, determine how many babies you are carrying and examine the early basic structural development of the fetus. Examples of circumstances when this may be applicable are: declining to have prenatal screening for trisomy 21 and trisomy 18, Non-invasive Prenatal Testing NIPT has already been initiated, or the pregnant individual is carrying more than two babies triplets, quadruplets etc.

First trimester scanning is useful to identify abnormalities in the early development of a pregnancy, including miscarriage and ectopic pregnancy, and provides the most accurate dating of a pregnancy. Technique First trimester scanning can be performed using either an abdominal approach or a vaginal approach. Abdominal scanning is performed with a full maternal bladder, provides a wider field of view, and provides the greatest depth of view.
Vaginal scanning is best performed with the bladder empty, gives a much greater resolution with greater crispness of fine detail. In circumstances where both approaches are readily available, the greater detail provided by transvaginal scans usually outweighs other considerations, and is preferred.

For the majority of women, the week scan is a reassuring and memorable experience, but sometimes problems are found. Some findings may not be significant and will resolve themselves. Others can forewarn of problems that would otherwise not be detected until birth or even infancy.

It is important to remember that only some abnormalities can be detected by scan; others are difficult to detect and therefore may be overlooked by scan, while some do not develop until later in the pregnancy or after birth.
For the scans we used two ultrasound machines: Philips XD11 with a MHz from 5 to 11 weeks of gestation, for an average of 4 scans per patient. We calculated the gestational age in weeks, rather than in days, because for pregnancy dating, however measurement started at 9 weeks of gestation.
This was a prospective cohort study of first trimester pregnancies. Non-parametric tests and logistic regression models were used for comparisons of distributions and testing of associations. A total of patients were included, of which were singleton pregnancies, 51 were twins, and 2 were triplets total fetuses. Fifty-two patients had 61 losses. We built nomograms with the changes of the parameters evaluated in ongoing, as well as in pregnancy loss.
The YS reliably identified the occurrence of a miscarriage at least 7 days prior its occurrence. CRL and HR became abnormal at a later time in pregnancy and closer to the event. These findings have important implications for patient counseling and care planning, as well as a potential bearing on cost effectiveness within early pregnancy care.
