A friend of mine who is trying to achieve pregnancy and is watching all her bodily symptoms has noticed that her Fitbit heart rate charts corresponded to her manual basal temperature rise, spiking at the time of ovulation. And there is some scientific data to back it up. Good news to those who are practicing NFP.
