4 Weeks Pregnant: What`s Happening this Week?
Until this moment it`s possible for you to be pregnant without even knowing. When you are in your 4th week of pregnancy, the gestational age of your baby is of 2 weeks. Your body may start to show signs that you might be pregnant. You may start to notice the lack of menstrual cycle, you may experience frequent urination, your breast may increase in size and might become more sensitive, and you might start to experience morning sickness.
During the 4th pregnancy week, the fertilized egg will move towards the uterus to find a place that will become its home for the next 9 months. The “future baby” will find shelter on the uterine wall, this moment being known as the implantation. The cells will split in two: one group will form the placenta, while the other one will form the embryo. Also, at this moment your baby will develop in what it`s known as the notochord. This is the primitive organ of your future fetus and this where its brain will start to develop. Even from now his brain will be divided in 3 segments:
- The forebrain
- The midbrain
- The posterior brain
The narrow part left after the swelling of the notochord will form the spine and the baby`s nerves, which in time will spread everywhere.
At this point, your “baby” will have between 0.36mm and 1mm in length. It`s not a surprise that you don`t even know that you are pregnant. During your visit to the doctor, it`s possible that he`ll prescribe you some nutritional supplements with folic acid. It`s already common knowledge that folic acid helps the baby to develop and it also prevents the formation of spina bifida, an abnormal development of the baby`s spine. The folic acid is an essential vitamin B which can`t be produced by the mother`s organism and which needs to be taken on a daily basis.
