DALLAS If you're carrying high, break out the pink.

If you crave salty food, it's a boy.

Old wives tales abound, but the only way for a pregnant woman to really know if she's expecting a boy or girl is a sonogram about 20 weeks into pregnancy.

And even that is no guarantee.

I wanted to get that nursery decorated, Kristina Mitchell said. I wanted to pick a name. We were not the kind of couple that wanted to wait until we got to the hospital to name the baby.

Mitchell found out she was having boys two months before a sonogram confirmed it.

She found out by taking an over-the-counter test developed by two equally curious Plano mothers Rebecca Griffin and Teresa Garland who couldn't believe no one had developed such a procedure before.

In fact, in the 17th century, the way they found out if a mom was pregnant was to have her pee on wheat and barley. 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, Griffin explained. So we were like, 'Aha! There is a difference!'

Neither Griffin nor Garland is a scientist. But over lunch one day, they brainstormed about the idea, then hired a scientist to help figure out this mystery.

Thus, IntelliGender, the first in-home gender prediction test, was born.

How it works is a secret, but the idea is much like a pregnancy test. Instead of a strip, expectant mothers use a cup.

These mompreneurs claim their gender test is about 80 percent accurate, as early as 10 weeks into pregnancy.

And that isn't their only thought about women and conception.

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 advised. There's lots of resources out there to help along the way. We found some and here we are.

The two women haven't yet made enough to send all seven of their own kids to college. But IntelliGender is now sold in major drug stores.

That will make it convenient for Kristina Mitchell, should she ever find herself expecting a sibling for her two sweet boys.

I would probably cross my fingers that I got a girl result, she said, but I'd be happy with boys!
