Normally, if menstruation does not occur at the expected time and there is irregular, light bleeding, the first step is to go to the hospital for an early pregnancy test. If the test shows two lines, this indicates pregnancy. Pregnancy includes intrauterine pregnancy and ectopic pregnancy. In cases of ectopic pregnancy, there is generally also irregular bleeding and abdominal pain. Therefore, if the early pregnancy test is positive with two lines and there is irregular bleeding and abdominal pain, one must be alert for the occurrence of an ectopic pregnancy. At this time, you can go to the hospital for blood tests to check the HCG levels and progesterone, along with an ultrasound to comprehensively determine the situation. If there is no gestational sac within the uterine cavity and an abnormal mass is found outside the uterus, then hospitalization and appropriate treatment for the ectopic pregnancy are needed.
