  • The adventure begins: Week 1 symbolizes the beginning of pregnancy, even if conception has not yet occurred.
  • The monthly menstrual cycle: During this week, a woman’s body loses the uterine lining in preparation for a possible pregnancy.
  • Fertilization: If fertilization occurs, the egg will come into contact with the sperm within 24 hours, kicking off the process of producing a new life.

Pregnancy 2 Weeks:

  • The fertilized egg attaches itself into the uterine wall, signifying the start of the pregnancy.
  • Early development: A collection of cells called a blastocyst begins to split and divides to become the placenta and the embryo.
  • Human chorionic gonadotropin (hCG), the pregnancy hormone, may begin to rise, causing a variety of physical and emotional changes.

Pregnancy 3 Weeks:

  • Rapid cell division: As the embryo develops the central nervous system, heart, and digestive system, it continues to divide at a rapid rate.
  • Amenorrhea: The absence of menstruation is sometimes one of the first indicators of a possible pregnancy.
  • Home pregnancy tests may begin to produce positive results, confirming the presence of hCG in the body.

Pregnancy 4 Weeks:
