The baby is pushed from the uterus out through the vagina and into the world by contractions of the muscle. I think this is the answer........

Oxytocin is secreted by the posterior pituitary and is peptide/water-soluble. It stimulates contractions during childbirth and milk secretion during nursing.
Afterpains is the pain caused by uterine contractions experienced after childbirth.
False labor, or Braxton-Hicks contractions usually occur in the 2 weeks prior to real labor, especially with the first childbirth.
By contractions. Contractions open your cervix, which allows the baby to come through the pelvis. During the pregnancy hormones have made the bones softer so the baby can pass without injuries. This is why many women have pain in their hips and back and difficulties to walk during pregnancy.
The strongest indication that contractions are occurring in association with true labor is that the contractions begin to occur at regular intervals. This is contrary to Braxton-Hicks contractions, which are spontaneous, random uterine contractions that do not occur with actual labor.
Yes. Those are braxton hicks contractions. very normal. These practice contractions occur at various times during pregnancy, but can increase in intensity during your last month. They happen at random and are typically not painful. They do not dilate the cervix as real contractions do.
