If the patient wants to keep the baby, it is necessary to go back to the hospital every other day to take another HCG test to see if the concentration of HCG increases exponentially. If it doubles, the baby is developing well, and basically, ectopic pregnancy or embryonic arrest can be ruled out. If you do not want to continue the pregnancy, the embryo is very small at this time because you have not yet reached your menstrual period, so you can wait until about 40 days after menopause to go to the hospital for an ultrasound. If an intrauterine pregnancy can be detected under the ultrasound, a medical abortion can be performed or an abortion can be performed.
