A pregnancy test with one dark and one light that is barely visible is usually promising, and may be due to a low amount of human chorionic gonadotropin, which can be tested again with a urine test about 14 days after intercourse or with a blood test about 7 days after intercourse. If a woman’s pregnancy test shows one dark and one light that is barely visible, there may be a chance of pregnancy. If the pregnancy is short, the concentration of human chorionic gonadotropin in the body is low, and the pregnancy test is not sensitive at this time. It is recommended to repeat the urine test about 14 days after intercourse to confirm the diagnosis. If necessary, a blood test can be done around 7 days after intercourse for a more accurate value. Once the pregnancy is confirmed, an ultrasound is performed to determine if the pregnancy is intrauterine. During pregnancy, women should follow the doctor’s instructions and undergo regular checkups to see how the fetus is growing. If there is any discomfort, the woman should go to the hospital in time to have the diagnosis made by the doctor and cooperate with the doctor in treating the symptoms.
