The Physiological Changes During Pregnancy

Every adult woman is responsible for their body, and the decisions they make have an impact on their life and their health. However, there are times in life, pregnancy, when a person is deeply responsible for a new life in development. Safe signs of pregnancy are the presence of a fetus seen by ultrasound, listening to heart tones, touching parts of the fetal body and the presence of pregnancy hormones in the urine. After fertilization, measurable concentrations of hCG begin to emerge in the body after 7-10 days, which can be evidenced from the urine or blood of the woman. The immunological tests used today are mostly based on the use of latex particles. The presence of Human chorionic gonadotropin, the polypeptide beta subunit of which is used to prove pregnancy (abbreviated b-hCG) at a concentration of 25 mIU in the urine of a woman, equivalent to a period between the fourth and fifth weeks of pregnancy, can be demonstrated. A planned pregnancy presupposes a series of procedures that will contribute to the proper and complete development of the embryo. Each stage of pregnancy brings certain biological changes in the body of the woman. Pregnancy should last a minimum of 37 weeks, but it can take up to 42 weeks.
