A seamless , smart fetal monitoring garment and methods of using thereof. The system includes a knitted or interwoven garment having a multiplicity of conductive textile electrodes for sensing maternal and fetal electrical vital signals. The maternal and fetal electrical vital signals are selected from a group including maternal heart ,rate fetal heart rate and electromyogram (EMG) activities including uterine activities. The method includes wearing the garment , acquiring electrical mixed common, maternal and fetal vital signals from surface region of a pregnant woman, using the plurality of textile electrodes, optimally weighted summing- up the acquired signals , analyzing the summed- up signals to thereby extract the maternal signal and the fetal signal , including determining their heart rates , and including detecting- health hazards and in some embodiments, including detecting a uterine contraction sequence suggesting the need to be hospitalized for birth giving.
