If a pregnancy test shows two red lines of the same color, it indicates pregnancy. If a pregnancy test shows two lines, one dark and one light, it indicates the possibility of pregnancy, and it is necessary to do another test with morning urine after three days or five days. If the two lines are the same color, it is recommended to go to the hospital to have a blood test for HCG, mainly to rule out the possibility of biochemical pregnancy or ectopic pregnancy. If there are two red lines, an ultrasound is necessary to check whether the gestational sac in the uterus corresponds to the number of days of menopause and to rule out the possibility of staph.
