HCG is still very light after one month, mainly due to the short period of pregnancy. The level of HCG and other hormones in a woman’s body will slowly and gradually increase after pregnancy, which can be determined by blood test or urine test whether pregnancy appears. The HCG level is low at the beginning, so if the pregnancy is too short, you can go to the hospital for a review after a while, and the level of HCG in the pregnant woman’s body will double as time goes by. If the HCG level changes slowly or often does not grow, it is considered to be a pre-eclampsia miscarriage. It is necessary to observe the physical symptoms to see if there are bleeding problems because of embryonic dysplasia or fetal abortion, it is recommended to seek medical treatment in time and women should pay more attention to rest in early pregnancy.
