Every woman who is preparing to become a mother should conduct a pregnancy calendar (3 weeks of pregnancy, which, in fact, interests us - the term is very important and we will explain why later) - it will be useful to her throughout her interesting situation.
Take the calendar in hand and determine the beginning of the last menstruation. Obstetricians traditionally begin counting the forty-week pregnancy precisely from this day. Ovulation occurs 12-14 days after the onset of menstruation. Therefore, the third week of pregnancy - this is directly conception.
How a woman should behave after fertilization
The third week begins with the fact that the female body completely rebuilds its hormonal background. As practice shows, the most important development of the embryo is when the expectant mother does not know about her pregnancy. Of course, your body should be prepared in advance. There are a number of mandatory items that need to be fulfilled by a future mother. First, it is necessary to completely abandon alcohol and nicotine, this applies to passive smoking. Try to remove coffee and tea from the diet. Note that green tea contains more caffeine than strong coffee. Eat more vegetables and fruits that contain vitamins. Limit yourself in citrus. They can cause an allergic reaction. Naturally, can not do without a fresh curd. Cottage cheese is the future bones, nails and teeth of your baby. It is important to pay attention to all the medications that you take. Be sure to consult a doctor, perhaps he will offer you an alternative that will not harm the future child. Do not take even vitamins without medical advice. Believe me, doctors better know what vitamin and in what doses you need. If possible, exclude the X-ray from the examination. Try to stay in a well-ventilated place. Analyze the conditions of your work. Are they favorable for the most important stage of your life? Try to protect yourself from stress. The development of a new life within you directly depends on your lifestyle.
Pregnancy calendar at week 3 of pregnancy
Of course, it is very interesting to look into the womb and understand how a new life begins to develop within you.
After ejaculation, a large number of spermatozoa move along the fallopian tube towards the egg. Only one in a million spermatozoa reaches the final goal. After this, a complex chemical reaction immediately forms, which prevents other spermatozoa from getting inside. Its nucleus, which carries the genetic code of the father, rejoins the core of the egg - the genetic code of the mother. It depends on the set of chromosomes of the father - you will have a daughter, or a son. Now your future baby is named "zygote". Zygote - this is the very first cell of the future little man. The third week of pregnancy is characterized by a rapid growth of the embryo and an incredibly fast division of the zygote. 3 days after conception, the embryo consists of only 32 cells. When the third week ends, the number of cells reaches 250. If it continued to grow at such a rate, then at 40 weeks, by the time of birth, would resemble the size of an adult. In the meantime, by the end of 3 weeks your future baby has a size - only one and a half millimeters.
Organism of a woman
When the pregnancy calendar has reached the third week and fertilization has occurred - you are officially considered pregnant. A couple of days after fertilization, a germinal vial filled with liquid is attached to the uterus. Now the future baby is named "blastocyst." At this time, the woman's body begins to rebuild dramatically. One consequence is the cessation of menstruation. The mucous uterus begins to gradually envelop the fetal egg, creating a placenta. The placenta will protect the fetus, supply it with air and nutrients. Now the embryo will feed not modest egg stocks, but your organs and systems. Now your food is the food of your baby.
