LOS ANGELES -- Five years ago, Lacey Murga and her husband decided they wanted to have a baby.
But Murga's menstrual cycle had always been irregular — she had a hard time figuring out the best time to try to conceive. So she looked online for ways to track her fertility and boost her chances of getting pregnant.
A quick search led her to the world of period tracking apps and wearables that help users to monitor their cycles to determine when they are most fertile. The apps, which have grown in popularity over the last several years, predict a person's chances of conception on a particular day based on individual data the user plugs in daily, such as their temperature, ovulation test results and when they started their period.
