The most important thing is to monitor whether the blood HCG value for ectopic pregnancy, which is usually greater than 50 mmol/ml, will double up every other day. Ectopic pregnancies tend to have blood HCG values that rise only a little bit every other day and not doubling up. When treating ectopic pregnancy conservatively, it is important to refer to the blood HCG value. If the blood HCG is greater than 3000 mmol/ml, conservative treatment is not recommended clinically because the possibility of failure of conservative treatment is higher in this case. In the case of ectopic pregnancy, besides monitoring the blood HCG value, the main thing is to do an ultrasound examination to find out where the gestational sac is located outside the uterine cavity, and to find out whether there is a fetal bud inside the gestational sac and whether there is a primitive heart tube pulsation. The clinical diagnosis of ectopic pregnancy is based on the condition of the gestational sac, and early management is possible.
