Every night Alyssa Fox puts on her ovulation bracelet right before it's lights out.

Alyssa Fox, trying to become pregnant, "You just have to put it on, sleep with it, wake up and it tells you when you're fertile. So it's really, really easy to use."

She's 26-years-old and she's been married for four years.  Starting a family seemed like the natural next step.

"Because everybody always tells you when you're younger, 'oh, you can get pregnant anytime!' or 'the second you get off birth control pills, you can get pregnant.' so I was really shocked when that wasn't me!"

She was also shocked that a wearable, much like a Fitbit could actually help her get pregnant.

Meant to be worn while sleeping, it monitors skin temperature, resting pulse rate, breathing rate, heart rate and sleep, then charts it all on an app so Alyssa can see the window when her body is ovulating.

"When I was doing the ovulation kits, I would have like one or two-day windows.  So I feel like maybe I might have been missing time.  And so I'm hoping, obviously, for a successful pregnancy out of it."

Reporter,  "How accurate do you think they are?"

Dr. Rebecca Chilvers, fertility specialist, "I honestly think the accuracy of the LH predictor kit might be better."

Plano fertility specialist, Doctor Rebecca Chilvers hasn't recommended an ovulation wearable to any of her patients yet.

She says the wearables do track variables related to ovulation, but tried and true tracking products like LH predictor kits are still the go-to.

However, she believes wearable technology will play an essential role as a first step for women struggling to conceive.

Dr. Rebecca Chilvers, "I think it's a good place to start if someone is young and doesn't have known fertility issues or known gynecologic problems and they just want to get more in tune with themselves and have some data before they come see me."

Alyssa Fox , "I learned I wasn't sleeping as well, I was a lot more stressed out than I thought. My ovulation was a lot different than what I was thinking it was. so it's really taught me a lot about my fertility and also about my lifestyle and how I'm sleeping, which has really been helpful just to know my overall health."

Some insight into her health that Alyssa hopes will put her closer to the baby of her dreams.
