Episode Details

 In the olden days, and in some circle even today, women measure(d) something called basal body temperature, which is a core temperature that can be used to track ovulation, by measuring their temperature right when they wake up. It's the first thing you do --with a special thermometer that measured to at least one 10th of a degree, and to record it on a chart, maybe on your phone, maybe on actual paper to identify a subtle temperature shift. 

But those were the horse and buggy days of biohacking for fertility. Now we can wear a ring that provides a continuous readout of your temperature and sends it to an app on your phone. And not only can it tell you if you are ovulating. It may be able to tell you if you're pregnant BEFORE the tests you can get at the pharmacy.

Today we talked to Dr. Benjamin Smar PhD, who has used sensor data to uncover some of the dynamics of your body in pregnancy.
