Changes occur during 3rd week of pregnancy

Baby's Development -

Even though woman may not feel that she is pregnant. The fertilized egg goes through a process of cell division. About 30 hours after fertilization, it divides into two cells, then four cells, then eight, and continues to divide. It moves from the fallopian tube to the uterus. This group of cells is called a morula. The morula becomes hollow and fills with fluid — it is then known as a blastocyst. Near the end of this week, the blastocyst will attach itself to the endometrium (lining of the uterus). This is called implantation

The implantation in the uterus produce an essential connection. The endometrium will provide the nutrients and will remove wastes. Over time, this implantation site will develop into the placenta.


Woman's Body -

Adequate intake of certain nutrients (such as folic acid, protein, calcium, and iron) is essential for nourishing baby. 
  • A folic acid supplement is important because folic acid helps prevent defects of the neural tube (the structure that helps in development to the brain and spinal cord), which forms very early in pregnancy. 
  • Intake of protein, which is used to create new tissue, should increase during pregnancy.
  • Calcium is necessary for the development of bones and teeth, so getting a good dose of dairy products, leafy green vegetables, and legumes. 
  • Iron is essential during pregnancy for increase of baby's blood volume. Good sources of iron include red meat, legumes, eggs, and leafy green vegetables.
