Can you tell which is which?

In today's world, most moms find out the sex of their baby before birth. The most common way to do that is via ultrasound, most frequently at around 18-20 weeks along. Often families wish they could know sooner, and while we're working on perfecting techniques as early as six weeks into pregnancy, it is not yet the standard of care. The timing of the ultrasound is purposeful, in that you can reduce the errors of mistaking girls for boys and vice versa.

(Yes, your ultrasound can be wrong.)

Finding out if your baby is a girl or boy can be fun with ultrasound. It is something people plan for in great detail. But long before the ultrasound, predicting girl or boy is something many parents play around with, often using old wives tales or so-called ancient methods like the ring test or the Chinese calendar. Sometimes parents are a bit more intense and wind up purchasing kits that supposedly tell the sex of the baby from about 10 weeks gestation through the mother's urine. Truthfully speaking, genetic testing is the gold standard, even compared to ultrasound. The problem is that amniocentesis and chorionic villus sampling (CVS) carry additional risks to your pregnancy.

Even though ultrasound is fairly accurate, there are often moms who are left wondering if the results they were given was right. That's why I've gathered up ultrasound photos from various stages of pregnancy.

Here you can either look ahead of your schedule and give yourself a crash course in telling the boys from the girls, or you can come back later and compare your own photos to those in the gallery.

No matter what you are looking for, you are sure to find a good example that looks similar to your photos.

But, if you feel like you'd like a bit of guidance, we have a great community of moms and professionals who love to play around with ultrasound photos.

The next thing to do will be to plan how to do your gender reveal! Will you find out right then at the ultrasound? When will you tell your friends and family? Will you keep it a secret for a bit? Or are you the type who wants to throw a party and do a gender reveal themed baby shower?

That said, sometimes you will have your ultrasound and be told that your baby is a boy when you had your heart set on a girl or vice versa. This is called gender disappointment. You are not alone here. Many moms feel some degree of sadness to outright depression. These moms share their stories to help others and to create support.

These ultrasound photos are great to look through for a variety of reasons. Perhaps you want to look at other photos to see if you can compare yours to other girls or boys. Maybe you want to get a heads up on telling the males from the females so that when you go to your ultrasound, you've got a leg up and can actually tell the baby's sex on your own. Or maybe you just are curious about the skills of the ultrasonographer.
