7 weeks pregnant: doubts? All you need to know!

At 7 weeks of gestation , it is possible that the woman already begins to notice weight gain, in addition to other characteristic symptoms. The embryo continues its development very quickly and takes the form of the future baby. At this point it can already start moving, although the mother will not notice it yet. During this week, it is recommended that a woman consider making a visit to her gynecologist for her first ultrasound.

Baby development at 7 weeks gestation:

At 7 weeks of gestation , the embryo has a gestational age of 5 weeks, since gestation starts counting from the day of the last rule, i.e. 2 weeks before the embryo ‘s conception . Furthermore, the size of the embryo is approximately 1 cm and it continues with organogenesis, that is, the development of all its organs and body systems. The changes the embryo experiences during the seventh week are discussed below:

  • The brain already has both hemispheres and neurogenesis takes place. At this time, about a billion neurons are produced.
  • Facial features are increasingly evident: the eyes have color, the eyelids appear, the nose begins to appear with the nostrils, the cavity corresponding to the mouth appears at the beginning of the digestive tract, etc.
  • The heart has two chambers and beats at a more regular rate.
  • The liver , pancreas and bronchi are formed and begin to function. The liver is responsible for producing blood cells because the bone marrow has not yet formed.
  • The skin is very thin, almost transparent.
  • The arms and hands are intuited, but the fingers have not yet appeared. The bumps on the legs begin to grow.
  • The embryonic digestive tract is formed, which is joined to the umbilical cord.
  • The skeleton acquires its shape and the tissue that will form the future vertebrae appears.

Due to all these important changes, that  7 weeks of gestation are fundamental for the proper development of the embryo . Exposure to teratogenic agents can cause birth defects in the future baby.

What are the symptoms at 7 weeks of pregnancy?

There are no major changes from last week. It is likely that some symptoms will begin to improve or disappear, but it is common to continue with the same symptoms as in previous weeks. Next, we will discuss the typical symptoms of 7 weeks gestation :

  • Nausea, with or without vomiting.
  • Sudden mood swings
  • The burn arises as a result of the pressure of the uterus on the stomach .
  • light weight gain
  • Constipation , as intestinal transit slows down.
  • Headache and fatigue.
  • Frequent need to urinate due to pressure on the vegija.

Most of these discomforts usually last for the first few months. From the fourth month onwards, the symptoms of pregnancy disappear, with the exception of those related to an enlarged belly.

Your body at 7 weeks pregnant:

Your cervix won’t be showing yet, because your uterus hasn’t risen yet (it doesn’t go until the end of the first trimester ), but that doesn’t mean you aren’t feeling the effects of being pregnant. From nausea to swollen breasts, your body is getting ready to grow your little one!

Swollen breasts:

Some women have climbed a full cup by 7 weeks gestation , which would be great if they weren’t so uncomfortably bloated and sore. Of course you can thank those pregnancy hormones for that. Ft is also accumulating in her breasts and more blood flowing to them. You may also notice that the areola (the dark area around the nipple) has gotten darker and larger and has small goose bumps. These are the sweat glands that provide lubrication for all the important changes when you start breastfeeding.

An extra glowing skin:

You may notice that your skin is better than ever, and your hair is shinier than the time you spent a fortune on Moroccan oil. These are both for the extra estrogen you’re producing right now.

What to do when you are 7 weeks pregnant:

One thing you should look out for is bleeding, whether in the form of dotted or smeared light, or a lot of blood. Bleeding in the first trimester is very common (affects about one in three women) and does not always indicate a miscarriage.

If you notice bleeding, you should see your doctor right away. Also, your doctor or obstetrician will be able to examine you vaginally and probably through an ultrasound. In most cases, the bleeding goes away and the doctor cannot explain it unless it is caused by an infection.
