It is normal for the blood HCG to double every other day in early pregnancy. If it doubles or even triples every other day, it is recommended to rule out the possibility of staph. If the blood HCG value is more than 100,000 mIU/mL, it is suspected to be staph and it is recommended to have an ultrasound examination as soon as possible. If the gestational sac can be seen in the uterine cavity and the yolk sac can be seen, or if the germ can be seen clinically, it is normal. If the yolk sac or germ is not clinically visible and the uterine cavity is covered with grape-like structures, this is a case of gravidity and early removal of the uterus is recommended.
