Jeff and Tyra Mclain desperately wanted to have a baby.

"You have to plan it you have to look at the calendar. It becomes no fun after a while."

Tyra knows the drill...messy pregnancy kits or trying to count down the days with a thermometer.

After 4 years of trying, all efforts failed.

"I was just tired, crying you know upset.

Then last September, Tyra tried something new.

It's an OV watch, a no hassle fertility predictor, you wear like any other watch.

On the back, sensors are constantly measuring your skin's salt levels. An early warning you’re about to ovulate. The watch gives you a signal; you have 6 days to conceive.

"Sperm survive for days at a time in the genital tract. So it's really not important that you know the day. It takes a lot of the pressure off."

Because of the watch, Tyra and Jeff tried conceiving earlier in her cycle...and it worked.

"He looked at me and I said we are pregnant. And he was like oh my gosh."

The watch, which costs close to $200, hasn't convinced all doctors.

Dr. Aaron Lifchez
Fertility Doctor
"Whether it truly increases the chances of getting pregnant in any one cycle still it's clear."

But the Mclain's think the watch is the reason they're now counting down the days to a new arrival.
