pregnancy:

  • Pregnancy occurs when a female egg meets a male sperm to become a fertilized egg.
  • This fertilized egg implants in the wall of the cervix to begin forming the fetus, which will turn after nine months into a small baby.
  • The placenta forms the only link between the fetus and the outside world, and from it obtains the materials that help it grow and form the elements of its body.
  • That is why a woman must take care of her nutrition and the nutrition of her fetus, and she should stop taking birth control pills if she is sure of her pregnancy.
  • The woman and her fetus undergo various physiological changes, starting from the first week of pregnancy until the time of the birth of the newborn.

Calculating the weeks of pregnancy:

  • Pregnancy weeks can be calculated in a simple way by considering every 4 weeks as one month of pregnancy.
