Pregnancy Encyclopedia – Understanding Week 4

Fourth week of pregnancy is the time to confirm things especially if you haven’t got any news. Here’s what to expect and do for the fourth week of pregnancy. You have been carrying your baby for over four weeks. Since pregnancy is calculated from the date of your last period, you are already one month pregnant. At this stage, the embryo is developing from two layers of cells to three.

The Baby

Your baby will be less than 3 mm long. At this stage, a part of the brain and the central nervous system starts to develop. Your baby begins to undergo magical transformation. Form a tiny ball, it transforms into a multilayered embryo. Yes, now the baby is called an embryo and consists of two layers known as the epiblast and the hypoblast. The amnion sac and yolk sac’s development starts in this week.  The amnion sac fills with amniotic fluid that offers protection to the embryo. The yolk sac produces the blood and helps nourish the embryo until the placenta takes control. The vascular network of your baby grows and helps in transporting blood, oxygen and nutrients from mother to baby through the umbilical cord. The heart of baby beats and blood starts to pump and organs also develop.

Your Body

By the fourth week, your body starts to change. The change is noticeable by you. Some of the most common symptoms include tender breasts and slight bleeding. Women experience bloating due to the progesterone hormone. It’s helping to slow down your digestion to allow more nutrients to enter the bloodstream and reach your baby. Some women may even observe that their smelling senses have become quite sharp.  A foul smell can lead to other symptoms such as nausea or vomiting.  Some of the symptoms may make you feel puzzled. The first trimester is actually a roller coaster ride. At 4 weeks pregnant, your body produces the pregnancy hormone HGC. This is the major reason behind most of the pregnancy symptoms.
