Even though pregnancy is a wonderful experience, it also comes with a a number of questions, especially if you are expecting for the very first time. Some of the questions that might crop up are, what foods should I eat, what type of exercises I should do, how my baby is developing and what changes will I experience every week . Learning about your pregnancy week by week can be extremely beneficial for you and your baby.
During the third week of your pregnancy the sperm and egg unite in one of your Fallopian tubes to form a one-celled entity. It is called a zygote. The third week is all about fertilization, whereas fetal development week 4 deals with implantation. During this period, the zygote reaches the uterus and divides cells rapidly. They form inner and outer group of cells – the inner group becomes the embryo while the outer group becomes the cells that protect and nourish the embryo. This process is called implantation. At this stage, the placenta that nourishes your baby also starts to form.
Fetal development week 5 is the time when the embryonic period begins. At this point, the brain, spinal cord, heart and other organs of your baby start developing. The embryo during this week is made of 3 layers. The top layer forms your baby’s outermost layer of skin, central and peripheral nervous systems. It also forms eyes and the inner ear. In the middle layer your baby’s heart and a circulatory system develops. While the inner layer is where your baby’s lungs, intestines and bladder will form. At the end of week 5, your baby is about the size of the tip of a pen.
During fetal development week 6, the neural tube closes. Your baby in this week is developing at a rapid pace. It is during this week your baby’s heart will start to form and begin beating. In addition to this, your baby’s brain will begin to divide into five parts. No matter what week you are going through, it is essential that you take care of yourself with the right diet and regular visits to the doctor.
