Your pregnancy and baby guide
Already being the mom of two little boys, I was admittedly a bit disappointed at my week ultrasound with my third child when the tech said she thought it was a boy. I was thrilled, of course, he was healthy, but still deep down was hoping for a girl. Looking at my ultrasound photo, which you can see below. I would agree, my baby looked like a boy. So, I started doubting gender scan accuracy and wondering if ultrasounds can be wrong.
After looking to the internet for answers, it turns out that early ultrasound photos are often mistaken. Incorrect guesses of male more often than female even. There are two reasons early ultrasound photos can make a girl look like a boy. The first is simple. The ultrasound tech or doctor sees an umbilical cord between the legs and mistakes it for male genitalia.
This can actually happen at any gestational age, making a clear image pretty important if you plan to buy non-neutral gender baby goods. Second, many parents are aware that all babies start off appearing as the same sex. The misconception is that all babies begin female, and if there is a dangly thing between the legs, you have a boy.
During the early weeks of external gender development both male and female babies have a dangly part down there as well as a bulbous area. You can see a clear visual aid and explanation here. The bulbous area becomes either a scrotum or labia. Inexperienced techs often assume no penis means a girl. For a confirmed girl ultrasound typically you want to see 3 lines indicating the shape of a vagina. Again, this is why 3D ultrasound is generally more accurate in predicating gender.
In all four of my pregnancies, gender was very clear by weeks. There is also the angle of the dangle theory. Between 12 and 15 weeks when looking at a side view on the ultrasound if the dangly middle part is at a degree angle or greater with the spine, your baby is likely a boy. The 30 degree on the dot mark leaves you still without hints. With these early scans, normal Doppler ultrasounds are recommended.
After the 20 th week, 3D ultrasounds are generally more accurate.

Every pregnant woman wants to know her due date , and a due date that is calculated from her last menstrual period with a due date calculator often doesn't match the due date that is estimated by her first ultrasound also known as a sonogram. During an ultrasound, a technician will spread a warm gel over the lower part of your abdomen and then press a tool called a transducer against your belly to examine your fetus using sound waves. An image of your fetus will appear on an accompanying computer screen and while looking at this image, the technician will take some standard measurements from different angles and listen for a heartbeat. Don't worry: This type of exam is painless and risk-free, and seeing your baby for the first time will likely be an enjoyable experience. Naturally, one of the most common questions asked about ultrasound accuracy is: Just how accurate are the due dates that are predicted by an ultrasound? Evidence suggests that, in the first 20 weeks of pregnancy , the first ultrasound may be the most accurate tool for predicting when your baby will be born. Early ultrasound due dates have a margin of error of roughly 1. If you can't remember your last menstrual period date or if you have consistently irregular cycles, the doctor can use an early ultrasound to give you a fairly reliable due date.

This cross-sectional study included consecutive pregnant women receiving antenatal care at two tertiary health institutions in Enugu, Nigeria, from January 1, to March 31, The mean age of the women was Most ultrasound scans The majority of the respondents The worrisome confidence in ultrasound scan dating is a challenge to the prevention of prolonged pregnancy and its complications in our environment. Antenatal health education should discourage self-referral for ultrasound scan dating and emphasize its limitations in late pregnancy as well as the perinatal effects of prolonged pregnancy. Knowledge of the expected date of delivery EDD and gestational age is essential in the management of pregnant women. Both are important for optimal prenatal, intrapartum, and postnatal care. For instance, reliable information about gestational age and EDD is useful in assessment of fetal growth during the antenatal period. In clinical practice, the gestational age and EDD are often determined using the LMP, except when the discrepancy between the LMP-derived gestational age or EDD and that of early pregnancy ultrasound scan exceeds 1 week; in this situation, the ultrasound scan estimates are more reliable and should be used. Further, the rate of post-term pregnancy has been shown to decrease when early ultrasound scan is used in estimating the gestational age and EDD. The uncontrolled proliferation of ultrasound in Nigeria has further heightened the conflict between these two estimates of delivery date because pregnant women are increasingly having access to ultrasound scanning manned by various cadres of health workers, without information on its known limitations.
