3 Weeks Pregnant

Pregnancy is a normal event in almost every woman’s life, but this is a life changing event that can change your preferences, likes and dislikes completely. Your life will start revolving around your child in many ways that you cannot even fathom. You will wake up in hours you never even knew existed and you will sleep at times when you never thought you will sleep. Such is the change that can happen in your life when you become pregnant and have a child. Although, not major changes may occur in your life when you are just 3 weeks pregnant.

When you are 3 weeks pregnant, it is just the time when you have conceived. This is the period when the egg and the sperm are united and the egg gets fertilized. It is during this 3 weeks pregnant period when the first implantation symptoms will start. The 3 weeks pregnant symptoms are very important because it will mean that you are well and truly pregnant. The lack of implantation symptoms in the third week will mean that you have not conceived at all.

How Your Baby is Growing This Week?

The fertilization of your mature ovum with a healthy sperm has taken place in your body. After a few days, this fertilized egg starts its journey to reach the uterus where it implants itself to form a baby.

During this week, your baby is nothing more than a tiny ball of several hundred cells called the Blastocyst. These cells multiply rapidly to form the various parts of a developing embryo. A part of these cells which will later form the placenta already starts producing the HCG (Human Chorionic Gonadotropin), a hormone that indicates the ovaries to stop releasing any further eggs, also increasing the production of progesterone and estrogen in the body of the mother. These hormones help your uterus stay healthy and not shed its lining, thus stimulating the growth of the placenta in your uterus.

At the same time, amniotic fluid starts getting collected around the cells forming a sac which will later form the amniotic sac. This amniotic fluid cushions your growing baby throughout its developing months in the uterus.

The multiplying blastocyst starts receiving oxygen and other essential nutrients, and also excreting wastes from the primeval circulation system (a series of microscopic channels which connect your baby with the blood vessels of your uterine wall). By the end of  4 weeks pregnant, this task will be then taken over by the completely developed placenta.

Implantation

The week 3 pregnancy symptoms are drastically different from the preceding week and the following weeks. It is because this is the week when you conceive and there are implantation signs present.
