2 Weeks Pregnant
Usually a woman gets pregnant in the middle of the cycle, on the 14th day. While released by ejaculation millions of sperms move through the vagina to the fallopian tube. Several hundreds sperms move to the egg releasing their special enzyme and only one of them manages to break through the eggâ€™s defensive layer. This is actually the moment of conception. A chemical process takes place after conception that prevents other sperms to enter the egg. The sperm gets absorbed and its nucleus carrying the genetic information gets united with the eggâ€™s chromosome.
The babyâ€™s sex depends on a pair of two chromosomes that actually make the human cell. The sex cells of sperm and egg carry only one of the two chromosomes. The female egg has always got chromosome Ð¥ but male sperm has got either Ð¥ or either Ð£. If a sperm with chromosome X gets into the female egg you will have a girl. If it is with Y then you will have a boy. Thus a babyâ€™s sex depends on how hard the dad tries.
The fertilized egg gets divided in two, then to four; while dividing it moves through the fallopian tube to the uterus. By the time it arrives, it has grown to 30 of cells. Their accumulation or reproduction is called â€œmorulaâ€ in Latin, which means â€œMulberryâ€.
The sperm joins the egg. And it results in a larger cell (the one larger than the size of a salt grain) is formed which contains 46 chromosomes inherited from parents, 23 chromosomes from each one. Besides that the fertilized egg contains genetic set for the future person: height, sex, eye and skin color, hair, facial traits from either momâ€™s or dadâ€™s.
