This is an observational study of pregnant persons in threatened labor. The study device will record electromyography signals, then the signals will be examined to determine who is in true labor and who is in threatened labor. The two goals are: * To establish the thresholds for the Contraction Synchronization Index (CSI) and the False Labor Index (FSI) to be used by the Labor Status Monitor to diagnose in-Labor or Not-in-Labor for preterm patients with threatened labor * To obtain feedback from subjects and providers to assist with enhancing patient comfort and provider training.
