WEEK 7 OF PREGNANCY: THE FIRST SYMPTOMS ARE NOTED

We continue our journey through Pregnancy week by week, advancing one more week after having seen everything that happens in the 6th week of pregnancy. We are immersed in the second month, and we will discuss the characteristics of this week 7 of pregnancy.

After the pregnancy tests and the possible first ultrasound, we have confirmed the pregnancy, although our body does not seem to have become accustomed, the symptoms are accentuated and we are already getting to the idea that a new being develops inside us.

Immersed in the second month of pregnancy

If we have not done yet the visit to the gynecologistWe will probably do it in this or the next few weeks. On the first visit the doctor will commission a blood test, a urine test and a vaginal smear, in addition to taking the tension from the future mother, to be able to prepare the report of the pregnant woman and control any possible risk.

Confirmation of pregnancy, preparation of a woman's complete history, physical examination and analysis collection are the key points of this first visit to the gynecologist. Do not forget to keep our doubts prepared and a notebook where to write down all the recommendations, although in the consultation they are usually printed.

Although we are still in the key weeks for embryo growthWhen the risk of abortion is higher, many couples already decide to make the good news public.

Although each woman will feel different symptoms, it is likely that during this month you have nausea (with or without vomiting), aversion or cravings for certain foods, heartburn, swelling in the belly, frequent urination, tiredness and drowsiness and changes in the breasts (more evident in subsequent weeks).

Doubts prior to the confirmation of pregnancy give way to very different moods: Some women will feel fear and worry, others a great joy and encouragement ... And most likely, the same woman will experience all these feelings according to the day and the moment.

But what is going on inside us?

Five and six week embryos

The embryo at 7 weeks of pregnancy

The embryo at 7 weeks of pregnancy is five weeks old since fertilization occurred. We remember that this is so because when counting the weeks of pregnancy begins from the date of the last menstruation (40 weeks) but the fertilization of the ovum occurs two weeks later (then we talk about gestation of 38 weeks).

Five weeks after conception, the wall of the uterus has softened to allow the embryo to implant strongly. Another internal change is the enlargement of the cervical mucosa or mucous plug, which ensures that the cervix remains closed and isolated from the outside world throughout pregnancy.

We are in the organogenesis period, because from the different layers of the embryo the body's organs are forming. The exposure of the embryo to teratogens (agents that can induce or increase the possibility of congenital malformations) during these weeks (4 to 8), constitutes the most critical period of its development.

In this embryo that It is about one centimeter long and weighs less than one gram the buds or buds of arms, the plate of the hand and the lower limb in the form of a shovel are visible. The brain transforms into five areas and some cranial nerves are visible.

The heart continues to develop and now beats at a regular rate. The lungs also continue their development.

Tissue is also formed that has to become the vertebrae and some other bones. Blood travels through the major vessels. In addition, the embryonic digestive tract is formed with a hole corresponding to the mouth and the lower part of the intestine already present.

Starts on development of eye and ear structures. In what looks more and more like a face it is possible to glimpse a slight pigmentation in the iris of the eyes and two tiny windows corresponding to the future nose.

Little by little, the embryo is growing, we can increasingly differentiate its parts and in a few more weeks we will talk about "fetus". Its development continues unstoppable in the second month of pregnancy and the advances in embryo growth are spectacular. In a few days we continue to discover everything about pregnancy week by week.
