The speed and quality of embryo development are related to the quality of the fertilized egg. With guaranteed quality of the fertilized egg, the development of the embryo will also be good, and the HCG will double normally. If there are abnormalities in embryo development, the doubling of HCG will also be abnormal. Generally, HCG is proportional to the duration of pregnancy, which means that the longer the pregnancy, the higher the HCG doubling. So, how much is normal for HCG to double in two days?
Delayed embryonic development can lead to a slow doubling of hCG. Generally, pregnant women with delayed embryonic development experience a 0.66-fold increase in two days. The normal speed is to double in two days. In general, the daily growth range of HCG is between 40% and 55%, and the range where HCG doubles every two days is between 80% and 111%. As long as it is within this range, it is normal.
If a pregnant woman experiences ectopic pregnancy, the rate of HCG growth will be slow and there will be no discernible pattern. The growth rate of HCG in ectopic pregnancy is lower than 66%. There is no unified explanation for the growth of ectopic pregnancy, as the rate of growth varies from day to day, fluctuating from high to low. To determine the average increase in ectopic pregnancy days, it is necessary to observe for about a week or even ten days before making an analysis. Ectopic pregnancy may also have other symptoms. If discovered, do not study the rate of HCG anymore, and seek medical treatment promptly.
