HCG7000 more likely to be 4-5 weeks pregnant, women start producing HCG when the trophoblast of the fertilized egg is formed after conception, and plasma HCG values can be measured a day later, and the values change, and the value of HCG can reflect the development of the embryo. The value of HCG can reflect the development of the embryo. The value of HCG varies from week to week of pregnancy, but it is not possible to clearly determine the number of weeks of pregnancy of a pregnant woman. Because this value varies greatly from one individual to another, it is mostly used for comparison with oneself. The development of the embryo is determined by whether it doubles every other day. For example, in the case of poorly developed embryos, biochemical pregnancies, or ectopic pregnancies, the doubling of the value is unsatisfactory, and the value may even drop. Blood HCG values peak at 8-10 weeks of gestation and decline rapidly thereafter. As the development of the embryo is still unstable in early pregnancy, women with a history of adverse pregnancies can monitor the blood HCG and progesterone values dynamically to observe the development of the gestational sac. Progesterone supplementation may also be given if progesterone values are low.
