HCG double can rule out ectopic pregnancy?

Usually the HCG value of ectopic pregnancy will be very low, so when the HCG value doubles, it is good to rule out ectopic pregnancy, but it should also go to the obstetrics department of the hospital to do B ultrasound examination to determine whether there is a gestational sac outside the uterus. For women in early pregnancy, they should pay attention to rest, timely supplement folic acid, and ensure adequate sleep.
