Pregnancy tests can still detect pregnancy after a pregnancy stoppage, but it is recommended to go to the hospital for an ultrasound to confirm the diagnosis. The principle of pregnancy test is to detect the HCG level in urine to determine whether a woman has pregnancy symptoms. The estrogen and progesterone, including HCG, in a woman’s body will not return to normal quickly after the onset of fetal termination, but will remain at a high level, so a positive result will still appear when using a pregnancy test. Fetal termination refers to the embryo in the early development process due to its own genetic defects, congenital embryonic anomalies or external stimuli and other phenomena to stop the development of the phenomenon, usually need to go to the hospital for ultrasound examination, to confirm the diagnosis of whether or not it is a fetal termination. Women should go to the hospital for an ultrasound to confirm the diagnosis after using a pregnancy test. If there are symptoms of fetal arrest, early surgical treatment is recommended.
