The first symptom to appear is intermittent painful uterine contractions followed by expulsion of blood stained mucus (show) per vaginam. Only few drops of blood mixed with mucus is expelled and any excess should be considered abnormal.
The pains are felt more anteriorly with simultaneous hardening of the uterus which is bodily pushed forwards. Initially, the pains are not strong enough to cause discomfort and come at varying intervals of 15-30 minutes with duration of about 30 sec. But gradually the interval becomes shortened with increasing intensity and duration so that in late first stage the contraction comes at intervals of 3-5 minutes and lasts for about 45 sec. The relation of pain with uterine contraction is of great clinical significance.
In normal labour, pains are usually felt shortly after the uterine contractions begin and pass off before complete relaxation of the uterus. Clinically, the pains are said to be good if they come at intervals of 3-5 minutes.
