We explain to you how your body evolves with four weeks of pregnancy and how your baby is growing. Let us help you clarify all your doubts.

Week 4 – 1st day

Growth and Development

The cluster of cells – now called the embryo – that is growing inside your uterus is the size of an apple seed. It divides into layers that later on form organs and tissues.

The neural tube – from which the brain, spinal cord, spinal cord and nerves will sprout – develops in the upper layer. The heart and circulatory system begin to appear in the middle layer. At the same time, a first version of the placenta (the chorionic villi) and the umbilical cord, which carries nutrients and oxygen to the baby, are already working. See more details

Week 4 – 2nd day

Symptoms

Your period is late and your breasts are enlarged and painful. All due to the beginning of production of progesterone, the main hormone of pregnancy, and the blastocyst (stage of the human embryo) that was implanted in the wall of the uterus. If you do an ultrasound, the gestational sac implanted in the fundus of the uterus and the yolk vesicle that carries nutrients to the embryo. Which is not yet visible, will be visible.

Week 4 – 3rd day

Gestation

This phase is very important to confirm if the gestational sac is in the right place. That is, inside the uterine cavity or if, instead, its implantation occurred outside the uterus. Which is called ectopic pregnancy , considered a medical emergency. The placenta an organ that connects its circulation with that of the embryo. Begins to take shape and clings to the wall of the uterus at the site of implantation. The umbilical cord exits on one side of the placenta. Amniotic fluid, which protects the baby during pregnancy, is forming inside this lining or membrane.

Week 4 – 4th day

Body and Health

The first four weeks are the period called “organogenesis”. That is, the formation of organs. Therefore, we must pay special attention to exposure to diseases or chemical substances. Avoid long periods in polluted places, especially where there is cigarette smoke, because although it may be indirectly aspirated, it can be harmful to you and the unborn child.

Reduction of oxygen levels, in addition to chemical components derived from petroleum present in polluted air from traffic, as well as other pollutants in the air that we aspire to, can influence both the formation of fetal organs and the placenta, as well as the incidence of respiratory diseases of the baby after birth.

Week 4 – 5th day

In pregnancy, your skin retains more moisture and becomes more moisturized. Soothing wrinkles and lines of expression. The rosy tone, especially in light-skinned women, is due to the increased amount of blood circulating in the body. The downside of this is that sometimes the coloring turns to “vermilion”.

Irritations to the skin become more visible and your face may become swollen due to fluid retention. It is no use reducing the intake of fluid to ease the swelling. On the contrary, drinking enough water in pregnancy is fundamental to health. The redness of the face will improve after the baby is born. If you want to hide it, Try using a moisturizing foundation, but never retinoic acid creams.

Week 4 – 6th day

Your Health

Stains called chloasma or “pregnancy mask”. They are caused by changes in pigmentation of the skin and can appear anywhere on the face or neck. In women with very dark or black skin, the spots may be lighter than the skin. Chloasma is caused by increased production of melanin. The hormone responsible for the tan, which protects the skin from ultraviolet rays.

Exposure to the sun leaves the spots darker. So if you have fair skin, wear sunscreen on your face every day and wear a wide-brimmed hat if you stay in the sun for a long time. If the spots are bothering you too much, try disguising them with a base. They will begin to disappear about three months after the baby is born. Folic acid deficiency can favor the appearance of blemishes. Therefore, use folic acid in foods (such as whole grains and dark vegetables) and taking a supplement (if directed by your gynecologist).

Week 4 – 7th day

Your Life

Just because you are pregnant does not mean that you are doomed to wear pastel robes or knit clothes. Black works great for future moms and is easy to match with anything.

Fashion consultants do not recommend a lot of striped fabrics horizontally. But if your favorite shirt still looks good, why not? Nowadays there are several options of stores that instead of “clothes of pregnant”, offer “pregnant fashion” for you to be beautiful!

Tips for your partner
