When one of the sperm successfully enters the egg, the next pregnancy process is when the sperm enters the nucleus of the cell that carries the genetic code, then fuses with the genetic code of the fertilized egg. Furthermore, the sperm determines the sex of the baby by the 46 chromosomes that make up the genetic characteristics.

The fertilized egg will then divide into 2 cells, and then develop into 4 cells. The egg cell will always develop. When the division of the egg continues, so will the cells move away from the fallopian tube towards the uterus. On this seventh day, which is after the fertilization process occurs.

So the cells that have been divided have reached 30 and this collection of cells is called the morula. The morula that has reached the uterine lining will be implanted in the endometrial lining. This growing group of cells will mature and become blastocysts, as well as stimulate changes in the mother’s body, including the cessation of the menstrual cycle.
