HCG 50,000+ is around 7 weeks of pregnancy. In the early stages of pregnancy, a woman can determine the chances of pregnancy and the early growth and development of the embryo by the degree of increase in the HCG value. Under normal circumstances, HCG will gradually rise 6-7 days after fertilization, and will rise to a peak at about 10 weeks of pregnancy, with a higher level followed by a slight decline and later stabilization at a higher level to maintain a normal pregnancy. HCG increase is also related to the number of days of menopause, the early and late implantation of the fertilized egg, and the development of the fast and slow, and it is not possible to determine the specific weeks of pregnancy by the degree of increase in the value of HCG, but also in conjunction with the days of menopause, the maternal health and the development of the embryo. The number of days after menopause and the gynecological ultrasound should also be taken into account to make a comprehensive judgment. When a woman suffers from chorionic villous lesions such as hyperemesis gravidarum, the HCG level can rise to hundreds of thousands of levels.
