The stood pregnancy is one of the most widespread pathologies of development of a fruit. Only the doctor can diagnose it. Even after death of an embryo the test for pregnancy can show 2 strips on an extent of several weeks.
The stood pregnancy, its signs and diagnostics
At the stood pregnancy there is a fertilization of an ovum, but at a certain stage the development of an embryo stops. Empty fetal egg can exist some time in a uterus then there is its rejection. Dying down of pregnancy can happens both on very early, and on quite late terms. If it occurs on term more than 28 obstetric weeks, this pathology is already characterized as death of a fruit.
The causes of the stood pregnancy can be much. Most of them are connected with bad heredity, the postponed earlier venereal diseases, with the use of medicines or alcoholic beverages. The risk of development of this pathology increases women with age.
To diagnose the stood pregnancy rather difficult. Only the expert can make it. Most often apply an ultrasonography method to more exact diagnostics. At the same time there are signs which give a reason to suspect the termination of development of an embryo. A disturbing signal is the sharp termination of toxicosis, decrease in basal temperature, bloody allocations from a genital tract can also appear.
What shows the test at the stood pregnancy
During normally developing pregnancy the standard house test has to show 2 strips. It is sign that fertilization occurred, the embryo develops and the organism develops a horionichesky gonadotrophin. Increase in concentration of HGCh in urine is the cornerstone of the principle of work of the test. Concentration of hormone in urine increases each several days. The more pregnancy term, the more authentically has to be test result. At the termination of development of an embryo the organism ceases to produce specific hormone, and its concentration in biological liquids begins to decrease gradually. Speed of decrease in concentration is individual for each case. It can depend on various reasons. At once after a stop of development of an embryo the test will still show positive result if concentration of HGCh in urine was sufficient for pregnancy definition. If at the time of pregnancy dying down its term was very small, in 2-3 days the test will show negative result. If the stop of development of an embryo occurs on later terms, time is necessary in order that concentration of a horionichesky gonadotrophin went down so that the test showed negative result. In medical practice cases when the express analysis gives positive result on an extent of month after death of an embryo and its rejection meet. Experts assure that the positive value of the test cannot serve as a guarantee that pregnancy develops normally. At emergence of any disturbing symptoms it is necessary to see a doctor.
