The development of the fetus lasts approximately 40 weeks. During this period the fetus, which was initially just an embryo formed by a set of cells, constantly develops until it becomes a fully formed baby. This process is marked by intense transformations that take place in the fetus itself and in the mother's organism.
Just 10 days after fertilization, the embryo is formed and developing. It is after the 12th week of gestation that a fetus is considered. The areas that will transform in the brain and spinal cord begin to develop as well as the heart and the main blood vessels, around the 16th or 17th day, and already on the 20th day the heart starts to pump liquid through the blood vessels and the first red blood cells and red blood cells appear the next day.
Fetus development - 1 to 12 weeks
In the first trimester of pregnancy, a period that corresponds to weeks 1 to 12 of gestation, the fetus goes from a few millimeters to 8 centimeters, weighing about 30g. In this period, although it can already be easily seen in an ultrasound exam, his body is still not very well formed, although it is already possible to perceive the shape of the head, trunk and limbs.
Fetus development - 13 to 24 weeks
In the second trimester of pregnancy, between 13 and 24 weeks of gestation, the fetus develops more and begins to measure about 25 cm in length, weighing about 550 grams. At this stage of fetal development, he already has eyelashes and fingerprints that will mark his identity, he is increasingly similar to a newborn baby, but if born within this period he has little chance of surviving, although medicine has evolved a lot in this regard.
Fetus development - 24 to 38 weeks
In the third trimester of pregnancy, between 24 and 38 weeks of gestation, the fetus has grown and developed enough. At this stage it can reach up to 4 kg or more although the birth of babies weighing just under 3 kg is increasingly frequent, which is also due to stress and the mother's overactive life. During the entire development of the baby and he was very well adapted to the woman's body and at the end of the third trimester, the time has come to be born.
During the entire period of pregnancy the woman must be accompanied by the obstetrician, who must monitor the baby's development and care for her health like that of her mother. During consultations, the doctor will be able to clarify all the mother's doubts and help decide on the possibility of delivery, which can be cesarean or normal, the latter with or without anesthesia.
