Most expecting parents want to know as soon as possible the sex of their baby.
Usually that means waiting until the fifth month of pregnancy, but a new gender test claims to be able to detect whether a baby is a boy or girl at as early as two months.
Rebecca Griffin and Teresa Garland, two moms from Plano, Texas, invented the "Intelligender."
They say the test is actually an updated version of a method used centuries ago.
"In the 17th century, the way they found out if a mom was pregnant was to have her [urinate] on wheat and barley," Griffen explained.
"If neither one grew, she wasn't pregnant. If the barley grew, it was a boy. If the wheat grew, she was having a girl," she continued. "So we were like, 'Aha! There is a difference!'"
The Intelligender is now available over the counter in most drug stores and easy to use.
"(It) comes witha syringe, which is used to insert the urine into the test, and then you swirl the test, set it on a flat surface," Griffin said. "And then in five minutes, it's either going to match the orange for girl or green for boy."
The ladies say Intelligender is 80 percent accurate.
Intelligender works as early as eight weeks into pregnancy, which is great for people who wanted to get a head start on preparations.
Kristina Mitchell said she used Intelligender to find out what she was having.
"I wanted to get that nursery decorated. I wanted to pick a name," Mitchell recalled about her pregnancy. "We were not the kind of couple that wanted to wait until we got to the hospital to name the baby."
Intelligender is a breakthrough in an untapped market and proof that anyone can make it big in business.
"If you're a mom out there and you've got an idea, and you want to try and make it happen, go for it," Garland said. "There are a lot of resources out there. We found some, and here we are."
The "mompreneurs" haven't made enough money to send their seven children to college yet, but there's still time.
