An ultrasound is a highly accurate means of dating a pregnancy. In a normal pregnancy, ultrasound can provide an estimate of the gestational age to within five to seven days of accuracy. In the first trimester, doctors usually use a transvaginal rather than abdominal ultrasound. The transvaginal ultrasound provides the most accurate information, given that the early developing gestational sac and fetal pole are extremely tiny at this point. A transvaginal ultrasound can get closer to the developing pregnancy. In a transvaginal ultrasound, the doctor or technician inserts a thin probe into the vagina. During the ultrasound, they take a series of measurements, including the size of the gestational sac, the size of the yolk sac, the length of the fetal pole, and the heart rate. In an abdominal ultrasound, the woman will be asked to come to the scan with a full bladder, because this positions the uterus in a way that makes it easier to obtain measurements. The doctor or technician then spreads a gel over the lower abdomen and uses a transceiver to take measurements from a number of angles.

It is common to be given a single ‘estimated due date’ EDD which corresponds the point at which it is estimated that your pregnancy will have lasted 40 weeks. 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. Many women with longer pregnancies find that everyone is asking whether they have had their baby yet, and that health care workers start to suggest inducing labour.
For some women this will be the right decision, but it is important to know that this is your decision to make. 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. There is a tendency for midwives and doctors to talk as though the EDD written in your maternity notes is something definite, rather than an estimate which may or may not be accurate.
In that case, if the EDD is later than it should be that could mean that the birth is delayed unnecessarily. This suggests that in general ultrasound dating is more accurate in predicting the birth date than counting from the last monthly period 1,2 but it is still only an estimate and may not always be accurate. A recent study 3 of women who conceived by IVF and therefore knew when their egg was fertilised, found that the routine ultrasound dating scan consistently put their estimated birth date earlier than it should have been by an average of 3 days.

It is also unlikely you will find out the sex with an NHS scan at 16 weeks, as generally, the only scans you are given in the first and second trimester is the week dating scan, where telling the sex is not possible, and the 20 week anomaly scan. Some private scanning places have deals which often include 4D peeks, teddy bears and photos, and even a little video of your bub moving around. And, if you want to make the sex a surprise, you can always ask the sonographer to keep it private, and write it down in an envelope for you so that you can have a reveal later on, with both private and NHS scans.
Though most places will not perform a gender scan on you until 16 weeks, sometimes you can see what you are having sooner. If the baby is in the correct position — with their legs open with a clear view from underneath — it may be obvious to the sonographer as early as 14 weeks, as by then the differentiation of male and female sex characteristics are complete. However, to tell the sex accurately, it is best to wait until between 16 to 20 weeks. However, in a study published by Fetal Diagnosis and Therapy , researchers studied sonograms from women who were all under 14 weeks pregnant.
They repeated the study when they were in the second trimester between weeks 18 and 24, when the sex can be determined by ultrasound. By this point, only women still met their study criteria, and were having girls, and were having boys. The average heart rate for boys in the first trimester was The nub theory is based on the fact that all embryos have a small bud or swelling called the genital nub, which is fixed at conception.
In a girl, the genital nub will become the clitoris and labia. You can see the genital nub on a scan image — but during the first trimester, the sex is really hard to see, and it can often be identified incorrectly. Of course, when finding out the sex of your baby, you want to be absolutely sure of it before you tell everyone.
