If there are two bars on early pregnancy test paper during menstruation, it indicates pregnancy, so the menstruation is not normal menstruation, but abnormal vaginal bleeding, and further examination is needed, such as taking blood to check the hCG and testing it again every other day. If the blood hCG can double on the original basis, it indicates intrauterine pregnancy, if the blood hCG only rises a little, it is likely to be ectopic pregnancy, so we must continue to give the examination and recommend hospitalization for observation, and ultrasound if necessary, mainly to know the location of the gestational sac, and then give appropriate treatment.
