You're Pregnant. Enjoy it!

3D / 4D / 5D Ultrasound - OAK PARK, IL and MCKINNEY, TX

But sometimes we can get a very clear picture of the gender of your baby in 3D.

Find out if you're Team Blue or Team Pink as early as 15 weeks.

Here is an example of a test question we give our ultrasound technicians during their training. Ultrasound technicians undergo over 100 hours of training before they are allowed to do the earliest of our gender checks.

Gender checks are done in 2D because 2D is more accurate.

Gender Check Guarantee


At First Peek Ultrasound, we have been at the forefront of checking gender checks as early as 15 weeks. 

We begin to check the gender of the baby starting at 15 weeks.  Although it is difficult to check the gender of the baby at this time, we want to provide this service to all the pregnant women who want to know as soon as possible.


What is your gender check guarantee?

The Gender Check Guarantee basically guarantees that we will tell you the gender of the baby, even if we can not find it during your first visit. Having to return the following week to determine the gender is rare (less than 10% of the time).

Being able to determine the gender depends on a variety of factors, including how far along you are in your pregnancy, the size of the baby, the size of the mother, whether you are having a boy or a girl, and the position of your baby.  Also, the position of the umbilical cord and the position of the placenta makes a difference.            We know that finding out the sex of your baby is very important.  If we can not determine the gender of your baby for any reason, you may return again within one month for no additional charge.  You can return as many times as is necessary for us to determine the gender of your baby.  This is our Gender Check Guarantee.

NOTE: Our Gender Check Guarantee does not apply if you come in to us before 15 weeks.


Is there a limit to how many times I can come in until i know the gender?
For as long as we are unable to determine the gender of the baby, there is no limit to the number of times you can come in for free to determine the gender. Of course, we hope to determine the gender within one or two visits, and three visits are very rarely needed.

If, in rare circumstances, we can not determine the gender even after 3 visits, we will give you the option of continuing to return again for free or issuing you a refund for the gender check if you wish.

DOes your gender check guarantee actually guarantee THE GENDER will be correct?
Determining the gender is never 100% until after the baby is born.  However, the gender check accuracy rate is over 99.9% (see Gender Check FAQ for more details). Nevertheless, if we determine the gender one way and you later find out that the gender is determined differently, please call us and, as a courtesy, we will recheck the gender for you and if we were incorrect, we will refund the price you paid for your gender check and allow you to come back to us for free for a Premium Package.  We offer the refund and the free Premium Package in order to assure our customers that getting the gender wrong, although possible, is a very rare event at First Peek Ultrasound, and we aim to make it as infrequent as possible.          


What if you get the gender of my baby wrong?

Please call us to let us know.  First, we will invite you to return to our clinic for free to recheck the gender.  In the event that we have called the gender wrong, we will provide you with a refund for the full amount of what you paid for your gender check package and will also allow you to come in for a free Premium Package.


Please note, ob/gyn physicians do not check the gender until at least 18 weeks, and usually not until 20 weeks, because their focus is diagnostic and medical ultrasounds.  In many cases, insurance companies will not pay for another ultrasound just to determine the gender if the         ultrasound is not medically necessary.  We are able to perform gender checks as early as 15 weeks because our focus is on gender checks and we have been performing gender checks as early as 15 weeks for over eight years.
