We continue our journey through the pregnancy week by week, advancing one week after having seen everything that happens in week 6 of pregnancy. We are in the second month, and we will try the features of 7 weeks pregnant.
Your baby measures between 0.44 and 0.52 inches (1.12-1. 32 cm). Its size has doubled during the last week, and although it is barely bigger than a peanut, they are beginning to form their hands and feet, and even have dots will be where your fingers.
At 7 weeks of pregnant, already his heart, lungs, kidneys, liver, pancreas, Appendix and bowels have been formed, although they are still original versions and have much to develop. His features facials, such as the eyes, mouth, and nostrils, are beginning to notice. His tongue and ears are also formed.
The head is the largest part of your baby's body since your brain requires the highest growth at this stage and generates about 100 brain cells per minute.
Umbilical cord, the tube that connects you to your baby until its birth, It is formed to reach the seven weeks of pregnancy. Yolk sac (their source of nutrition until now) it will soon disappear, and the umbilical cord will be responsible for transporting oxygen and nutrients to your baby, and eliminate waste.
In the first trimester of pregnancy, most of the changes in your body are given internally. These are some of the transformations to reach the seven weeks of pregnancy.
Your uterus has already doubled in size. The mucus plug, which is a protective membrane that seals your cervical canal is formed. The mucus plug will come off just before birth. Your blood flow also increases to meet the needs of your baby. Upon reaching the seven weeks of pregnancy, you have 10% more blood circulating in your body.
The only visible change is the growth of your breasts, which at this point can be measured one more size. And as they grow, it increases their sensitivity. Also, the veins surrounding them become more visible, and notes small eruptions on your areola (known as Montgomery glands).
After the possible first ultrasound and pregnancy testing, have confirmed the pregnancy, although our body does not seem to have been used, the symptoms are emphasized, and we are already making us to the idea that a new one be developed within ourselves.
If we haven't done a visit to the gynecologist yet, probably we do in this or the next few weeks. On the first visit, the doctor arranges a blood test, a urine test, and a vaginal smear, in addition to taking the blood pressure, in order to draw up the report of pregnant women and control any possible risk.
Confirmation of the pregnancy, the elaboration of the complete history of women, physical examination and the collection of analysis are the key points of this first visit to the gynecologist. Do not forget to bring our doubts and a notebook where scoring all the recommendations.
While we are still in the great weeks to the embryo's growth, when the risk of miscarriage is higher, many couples already decide to make public the good news.
Although every woman will feel some different symptoms, is likely to have this month (with or without vomiting) nausea, aversion or cravings for certain foods, the acidity of stomach, swelling in the belly, need to urinate frequently, weariness and tiredness and changes in breasts (most evident in the weeks after).
The questions before the confirmation of the pregnancy give way to very different moods: some women will feel fear and concern, other a great joy and encouragement. And it is likely that a woman will experience all these feelings depending on the day and the time.
The embryo to the 7 weeks pregnant has an age of five weeks since fertilization. We remind you that this is so because when the weeks of pregnancy begins from the date of the last menstruation (40 weeks) but the fertilization of the egg occurs two weeks later.
Five weeks after conception, the wall of the uterus has softened so that the embryo implant with force. Another internal change is the enlargement of the cervical mucosa or mucus plug, which guarantees that the cervix remains closed and isolated from the outside world throughout pregnancy.
We are in the period of organogenesis because the body's organs are forming from the different layers of the embryo. The exposure of the fetus to Teratogens (agents that can induce or increase the likelihood of birth defects) during these weeks (4-8), is the most critical period of its development.
This embryo that is around a centimeter in length and weighs less than one gram become visible buds or shoots of arms, hand plate, and the shovel-shaped bottom end. The brain turns into five areas, and some cranial nerves are visible.
The heart continues to evolve and now beats at a regular pace. The lungs also pursue their development.
Also, a tissue that has to turn into the vertebra and some other bones. Blood moves through the older vessels. Also forms the embryonic gut with a hole corresponding to the mouth and the lower part of the intestine that is already present.
He began the development of the structures of the eye and ear. In what increasingly looks more like a face, it is possible to envision a light pigmentation in the iris of the eyes and two tiny windows corresponding to the future nose.
Step by step, the embryo grows, and increasingly we can differentiate more parts and in a few weeks, we will talk of "fetus". Its development is unstoppable in the second month of pregnancy, and the progress in the growth of the embryo are spectacular. In a few days, we are still discovering all about pregnancy week by week.
