A company called Mira showed off its fertility monitor at CES earlier this year with the promise that it's much more accurate than the other digital trackers out there. Now, the technology is finally available for purchase worldwide. Mira's Fertility Starter kit comes with an AI-powered egg-shaped analyzer and 10 disposable test wands. Unlike the trackers that only tell you if you're ovulating or not, Mira tells you the quantity of Luteinizing hormone (LH) in your urine, which means you can use it to determine your peak fertility days. You only have to pee on a wand and stick it into the monitor to get your results.
