delayed menstruation, pregnancy-test-positive
menstruation delayed and negative pregnancy test is a combination occurring more often than we realize. This is because the drugstore pregnancy tests and blood tests used to diagnose pregnancy act by the same principle: the detection of a hormone called human chorionic, hCG. As only the beta fraction of hormônico is dosed, the blood test is called beta hCG.

This hormone begins to be produced about eight days after fertilization, just after implantation of the egg in the uterus and rises rapidly until the 10th week of pregnancy, when it falls and stabilizes. The concentration of hCG in urine is less than blood and the first weeks of gestation may not be detected by the test pharmacy, having negative bhgc. But the blood test identifies the hormone in minimal amounts.
The occurrence of bleeding during a small embryo implantation in the uterus is possible and occurs about fourteen days after fertilization, a period that may be confused with the time of menstruation.
Early diagnosis of pregnancy is important to start prenatal care, controlling blood pressure and glucose levels. Moreover, the recognition of pregnancy prevents the woman as the ingestion of alcohol and drugs that can be harmful to the fetus.
