How to diagnose pregnancy
The woman's body begins to prepare for pregnancy a few weeks before its occurrence. In the ovary, the follicle with the egg matures under the influence of hormones, and the endometrium (the inner mucous membrane of the uterus) expands so that the fertilized egg can implant. Approximately on the 14th day of the woman’s menstrual cycle, ovulation occurs, and if on that day the sperm cell fertilizes the egg, thenpregnancy. Within two weeks, the fertilized egg exists autonomously, moving along the fallopian tube toward the uterus. And only after 10-14 days it is implanted in the uterus. From this point on, the body of a woman under the influence of hormones begins to change, thanks to which it becomes possible to diagnosepregnancy.
The first sign of pregnancy is delayed menstruation. But, unfortunately, it can be caused by other reasons.However, pregnancy diagnostics can be performed starting from the first day of the delay. The most affordable and simple way to determine pregnancy is a rapid test. It is held at home and usually gives an accurate result. The principle of its action lies in the fact that after implantation of a fertilized egg in a woman's body, a special hormone is produced - chorionic gonadotropin (hCG). It is found in the blood and urine of a pregnant woman. The test when determining pregnancy reacts to him. If there is HCG in the urine of a woman, the test will give a positive result. In the absence of a hormone, the answer will be negative.
A more accurate way to diagnose pregnancy is to determine the level of hCG in the blood of a woman. This analysis is done in women's clinics and most private laboratories. According to its result, it is possible to judge not only the presence of pregnancy, but also its term.
Ultrasound examination allows you to see the fetal egg. The advantage of this diagnostic method is that it is possible not only to confirm the presence of pregnancy, but also to make sure that it is uterine.
