An ectopic pregnancy can be detected with a test paper. The test paper will show two red bars, indicating a positive pregnancy, but the test paper cannot tell if the pregnancy is intrauterine or extrauterine. Ectopic pregnancy also belongs to pregnancy, only that the location of the gestational sac is not in the uterine cavity, not in the normal position, which is an abnormal pregnancy, so women who test themselves pregnant after menopause must go to the hospital for ultrasound, if the ultrasound can see the gestational sac in the uterine cavity basically can exclude ectopic pregnancy, after all, the chances of pregnancy inside the uterus and outside the uterus at the same time is very low; if the ultrasound can not see the gestational sac, some of them are short of menopause, so you can review the ultrasound after a few days. If the progesterone value is low, the doubling of HCG every one or two days is not ideal, and the ultrasound indicates that there is no echogenicity of the gestational sac in the uterine cavity, but mixed echogenicity can be seen in the adnexal area, then ectopic pregnancy should be highly suspected. Ectopic pregnancy can be life-threatening if it ruptures, and it can cause severe abdominal pain and even fainting, and hemorrhagic shock can occur if there is excessive bleeding, so if ectopic pregnancy is suspected, it should be treated conservatively or surgically by hospitalization in a timely manner. In conclusion, as long as the pregnancy is intrauterine or ectopic, the test paper is positive, but you must go to the hospital for a repeat ultrasound and blood test for HCG and progesterone to rule out ectopic pregnancy, because the test paper cannot tell whether the pregnancy is intrauterine or ectopic.
