Types of pregnancy

There are three different types or classes of pregnancy:

Intrauterine PREGNANCY: this kind of pregnancy is the conventional or normal, ie, one in which the fetus is implanted in the uterus (hence its name) and power grows, without any alteration or complication.

Ectopic Pregnancy: A word ectopic means out of place and refers to that pregnancy that occurs outside the uterus of the mother. The embryo usually located in any of the channels through which the egg is directed to the ovary, such as fallopian tubes. Although it may also be placed in the abdomen, the same ovary, etc, and there is no possibility that the child may develop and survive in these conditions.

MOLAR PREGNANCY: this kind of pregnancy has the peculiarity that the egg was fertilized abnormally. From this, the placenta grows disproportionately and is transformed into a set of cysts called hydatidiform mole. As a result the embryo fails to form and does not survive.

Molar pregnancy should be interrupted only known of its existence.

There are two types of molar pregnancy:

complete molar pregnancy is one in which there is no normality in the embryo and placenta tissue. Moreover, all the chromosomes of the egg belong to the father, when current is that half are from the mother and the other half come from the father.

Partial molar pregnancy: here the placenta may show signs of normal, and the embryo develops abnormally. In addition, half of the chromosomes come from the mother, but those who belong to the father appear in two groups. Consequently the fetus, instead of present 46 chromosomes, containing 69.

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.
