Ectopic pregnancy is usually detected as early as 6 to 8 weeks of pregnancy. With a normal menstrual cycle, a visible gestational sac can be seen in the uterine cavity by ultrasound six to eight weeks after conception. If the gestational sac is not seen inside the uterus, consider the possibility of an ectopic pregnancy. Ectopic pregnancy can be diagnosed when an abnormal mass is found outside the uterus and an abnormal hypoechoic sound is detected in the parietal region with a yolk sac, fetal buds, and fetal heartbeat. If the ultrasound can not see the case, you can also indirectly determine whether the ectopic pregnancy through the blood test. Under normal circumstances, if the pregnancy is normal, the blood chorionic gonadotropin value is rising rapidly, and progesterone is also rising gradually. In the case of ectopic pregnancy, the HCG values and progesterone will be lower. If a gestational sac is seen in the uterine cavity consider it an intrauterine pregnancy and have regular labor tests. If there is abdominal pain, vaginal bleeding, and the examination is ectopic pregnancy, you should be hospitalized to terminate the pregnancy.
