Week 3

Development of 3 weeks fetus

How does a 3-week fetus develop?

Although the mother may not feel she is pregnant yet, but surely now a baby is growing and developing inside the mother . Although only a 3 weeks old fetus, but the baby is currently developing to its full potential. The fertilized egg goes through a process of cell division. About 30 hours after fertilization, the egg will divide into two cells, then four, then eight and continue to divide until it moves from the fallopian tube to the uterus. When they reach the uterus, this group of cells will look like a small balloon and are called an embryo.

The embryo becomes empty and filled with liquid, known as a pocket of the embryo. The blastocyst then attaches itself to the endometrium. This is called implantation. An implantation in the uterus creates an essential connection: the endometrium provides nutrients and removes waste from the developing embryo. Over time, this transplant area will develop into the placenta.

It's usually pretty easy to gain weight back because nausea and vomiting should go away between 12 and 14 weeks of pregnancy. What causes morning sickness is still not known for sure.
