Before true labor begins, you may have false labor pains, also known as Braxton Hicks contractions. These irregular uterine contractions are perfectly normal and may start to occur in your second trimester, although more commonly in your third trimester of pregnancy.
When the contractions are regular and in short intervals and the cervix is dilated labor has begun. Labor, parturition, begins with the onset of complex interactions between the placenta and fetus, triggered by the mother. Progesterone form the mother inhibits contraction of the uterus; the effects of progesterone are countered by a sharp increase in estrogen towards the end of pregnancy.
