If the blood HCG is 100mIU/ml after the clinical blood test, there are several clinical possibilities: the first one is normal pregnancy, it is recommended to take another blood test every other day, if the value of blood HCG has doubled on the basis of the original, it indicates a high possibility of intrauterine pregnancy. Secondly, if the blood HCG does not double after the second day of blood sampling, but only rises a little, and the progesterone is relatively low, then the possibility of ectopic pregnancy is very high, and we suggest hospitalization for observation and further examination. Thirdly, it is clinically possible that the pregnancy is a staph. After the clearance, the blood HCG shows a tendency to decrease before it reaches 100mIU/ml, and if monitoring continues and it continues to decrease, it is a benign cycle in clinical terms.
