False labor occurs when Braxton Hicks contractons become more rhythmic and occur in hte lower abdomen. These contractions are intermittent non-productive muscular contractions of the uterus usually in the last two months before full term. These contractions are non-productive and do not produce any flattening (effacement) or dilation (opening up) of the cervix. An episode of false labor can be of great concern to a pregnant woman, especially when she experiences these contractions for the first time. However, these contractions are of limited duration and do not indicate the onset of active labor.
