Miscarriage identification and prediction from wearable-based physiological data

An apparatus, comprising:

• a processor;
• memory coupled with the processor, and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• acquire, via one or more temperature sensors of a wearable ring device configured to be worn by a user that is pregnant, physiological data associated with the user;
• receive, via a transceiver of a user device and from the wearable ring device, the physiological data associated with the user, the physiological data comprising at least temperature data;
• determine a time series of a plurality of temperature values taken over a plurality of days based at least in part on the received temperature data;
• identify that the plurality of temperature values are lower than a pregnancy baseline of temperature values for the user based at least in part on determining the time series;
• identify that one or more positive slopes of the plurality of temperature values are lower than a positive slope of the pregnancy baseline of temperature values for the user based at least in part on determining the time series;
• detect an indication of an early pregnancy loss of the user based at least in part on identifying that the plurality of temperature values are lower than the pregnancy baseline of temperature values for the user and based at least in part on identifying that the one or more positive slopes of the plurality of temperature values are lower than the positive slope for the pregnancy baseline of temperature values for the user;
• and
• generate a message for display on a graphical user interface of the user device that indicates the indication of the early pregnancy loss.

A non-transitory computer-readable medium storing code, the code comprising instructions executable by a processor to:

• acquire, via one or more temperature sensors of a wearable ring device configured to be worn by a user that is pregnant, physiological data associated with the user;
• receive, via a transceiver of a user device and from the wearable ring device, the physiological data associated with the user, the physiological data comprising at least temperature data;
• determine a time series of a plurality of temperature values taken over a plurality of days based at least in part on the received temperature data;
• identify that the plurality of temperature values are lower than a pregnancy baseline of temperature values for the user based at least in part on determining the time series;
• identifying that one or more positive slopes of the plurality of temperature values are lower than a positive slope of the pregnancy baseline of temperature values for the user based at least in part on determining the time series;
• detect an indication of an early pregnancy loss of the user based at least in part on identifying that the plurality of temperature values are lower than the pregnancy baseline of temperature values for the user and based at least in part on identifying that the one or more positive slopes of the plurality of temperature values are lower than the positive slope for the pregnancy baseline of temperature values for the user;
• and
• generate a message for display on a graphical user interface of the user device that indicates the indication of the early pregnancy loss.
