If your period is delayed for 1 day, a urine HCG test with 2 lines, one dark and one light, indicates the possibility of pregnancy. If there is no vaginal bleeding, no pain in the lower abdomen and no other symptoms, you can test again after 5 days using morning urine. If there are still two lines, one dark and one light, it is recommended to go to the hospital to have a blood test for HCG, and depending on the condition of the blood HCG, the test can be repeated every 1 day to make a preliminary diagnosis. In addition, if 2 lines of the same color appear, go to the hospital for an ultrasound examination at around 45-50 days of menopause to find out the location of the gestational sac.
