The pregnancy

It is known as pregnancy the control period time ranging from fertilization of the ovum by the sperm, until the time of delivery. In this physical processes of growth and development of the fetus in the womb of the mother and also the important changes experienced by the latter, in addition to morphological and metabolic physicists are included.

Human pregnancy lasts a total of 40 weeks equivalent to 9 calendar months. In gilts, as referred to women who give birth for the first time and where not, but are less likely, the first trimester of pregnancy turns out to be the most risky because of the possibility of loss thereof (spontaneous abortion). Meanwhile, once the point of viability of the fetus and the third begins, this means that the baby is already able to survive extrauterinamente without medical support. While the technical means available differ depending on resources and social factors, it is estimated that a fetus at 24 to 26 weeks would be able to survive with proper medical care. These children are called extremely premature. In contrast, infants with gestational age more (30 or more weeks) could survive with a lower level of care complexity, as long as the lungs have reached the necessary maturity.



Among the most common and normal symptoms that anticipate or advertise this moment awaited by couples who decide to have children are the absence of menstrual periods or amenorrhea, hypersensitivity nipple, increased breast size, drowsiness, morning vomiting, dizziness, changes when they perceive odors used and the need to eat certain types of foods or food, most commonly known as cravings. Professional diagnosis of pregnancy is performed in the early stages of amenorrhea by the determination of a hormone, chorionic gonadotrophin, by known commercial kits for urine testing or measurement by blood.

Another sign that can also be an indicator of pregnancy is incipient and uncontrollable need to urinate all the time, usually hourly. This situation occurs due to the increased size of the uterus, where the future baby will stay until birth, which is oppressing the bladder. This carries the risk associated with a greater likelihood of urinary tract infections, which can lead to serious complications in pregnancy.
