Blood value generally refers to the blood HCG value, and the blood HCG value can be eliminated after about 8~10 weeks of IVF. Generally speaking, after in vitro fertilization, once the embryo completes implantation, the blood HCG value of the pregnant woman will increase exponentially, and through regular observation of the HCG value of the pregnant woman, it is possible to clarify the status of the pregnancy, determine the development of the fetus, and know whether there is any abnormality of the pregnancy, so most of the time it is necessary to follow up on the changes in the HCG value of the pregnant woman. In about 8~10 weeks of pregnancy, the blood HCG value of pregnant women will reach the peak, and then will gradually decline with the progress of pregnancy, and this period of time is also the beginning of pregnancy into the mid-pregnancy point, after the mid-pregnancy, the situation of the fetus is basically in the state of stabilization, therefore, usually in about 8~10 weeks, you can stop checking on the blood HCG value of pregnant women. After the IVF transplantation, you must follow the doctor’s rules and do every checkup, because the success rate of the transplantation is lower than that of the normal conception, and in order to avoid failure, you should also improve the bad habits.
