Second step: if the nub is over 30 degrees up from the spine, it’s a boy!. I am 17 weeks now – will be doing anatomy scan Jan 23rd and will, hopefully, find out for sure then and update thread : Thank you! Baby Gender Predictor More than half of the people want to know the gender of the baby before the baby gets born. The finest ring sampler to date, the Nub Anthology sampler contains a tasty conglomeration of sixteen cigars. By week 13 to 16 a very clear difference can be seen on ultrasound, but keep in mind, at 12 to 13 weeks the average baby is only the length of 2 pennies placed side by side and the genital area is the size of a pin head. Nub theory fans, however, claim that by 12 weeks the tubercle is different enough in appearance to be noted on an ultrasound. They also do a blood test and these two tests together will tell you the risk factor for your baby. Our ultrasound tech guessed boy at 13 weeks based on nub theory, and she was correct! I’ve included two photos, one of which according to the sonographer was my good “nub pic” I don’t really get this, despite scouring the internet!?
Obstetric ultrasound, also known as prenatal or pregnancy ultrasound, uses high-frequency sound waves to produce images of a developing embryo or fetus. Your doctor will use information from obstetric ultrasounds to track pregnancy progress, gestational age and help predict delivery dates. During an obstetric ultrasound, you will be on a bed, usually on your back.
You may be asked to change position during your scan. Changing position helps move your organs and the fetus into a better position so the sonographer can capture high-quality images. If you have an Alberta Health Care card or valid health care card from out of province, there is no cost for an obstetric ultrasound except in Quebec.
I’ve just been for my 12 week scan and they have told me I am 15 weeks i meant to add: dating scans are more accurate than LMP, as you can I would expect a 13 week fetus to be significantly bigger than an 11 week one.

Pregnancy math can be a little murky. After all, unless you went the IVF route, your physician has no way of knowing the exact time of conception. Because of this, pregnancy is calculated from the first day of your last menstrual period or LMP. From that day, weeks of pregnancy is officially counted, and your doc or midwife busts out the red pen and marks your due date on the calendar. Sometimes, however, the due date may be revised. It can be pretty difficult to determine a due date using the date-of-last-period method for women with irregular cycles — which is why an ultrasound exam is often required to determine gestational age.
An early ultrasound, usually done at about 6 to 9 weeks, can give the most accurate due date estimation by measuring the size of the embryo or fetus. However, many pregnancies are confirmed by a Doppler heartbeat monitor, not an ultrasound. Did you get your very first ultrasound in your second trimester? If so, that could be why your due date shifted. Ultrasounds performed during the first trimester not the second give the most accurate due date predictions, according to a study in the American Journal of Obstetrics and Gynecology.
The length of this is approximately the size of your uterus and closely correlates to how far along you are.

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.
Your health care provider will schedule your NT ultrasound at a hospital or a clinic with a certified NT sonographer or physician.
