The reference range of normal value of HCG in 35 days of pregnancy is about 1000-50,000 IU/L, the specific value varies from person to person, the HCG value of each woman has some differences, the rise of HCG in this period is very large, the interval of about 2 days can basically reach doubling. The change of HCG in early pregnancy is more critical, it is recommended to recheck HCG every other day, if it can double every other day, it generally indicates that the fetus is developing well. If the HCG is too low on the 35th day of pregnancy, the possibility of delayed fertilization of the egg is not ruled out. If you have stomach pain and bleeding, it is recommended to go to the hospital in time to have blood tests for HCG and progesterone, so that the doctor can diagnose whether the HCG value in your body is symmetrical with your own pregnancy time. If the HCG value is measured too low on the 35th day of pregnancy, it may be a precursor of miscarriage or embryonic dysplasia. During early pregnancy, it is recommended to enhance dietary nutrition, such as eating lean meat, eggs, milk and soy products, supplementing folic acid products, avoiding spicy and stimulating foods, and avoiding strenuous exercise and intercourse during pregnancy to prevent triggering miscarriage.
