Week 40. Pregnancy week by week

Changes in the pregnant woman: week 40 of pregnancy

We began this 40th week of pregnancy as we finished the 39th, with special attention and remembering the Pre-delivery symptoms:

1. Rhythmic, regular contractions (every 5 minutes) and even painful.

2. Bleeding greater than or equal to menstruation.

3. Breaking the bag or amniotic sac (The amniotic fluid can come out in more or less abundant amounts). It is important that you notice the color and appearance of your amniotic fluid. If the liquid is transparent, everything goes well, however if it has a yellowish or greenish color it is urgent that you communicate it to your doctor.

Although it is not known exactly what produces childbirth, it is known that the fundamental role is played by a hormone: oxytocin. When the baby's lungs are mature, they secrete a protein into the amniotic fluid that disrupts the production of hormones. This change causes the placenta to reduce the emission of progesterone and instead promotes the production of oxytocin, which regulates contractions of the uterus.
