The presence of one dark and one light on the pregnancy test paper suggests a weak positive, which should be related to the small number of days of pregnancy, and the chance of pregnancy can be about 70%-80%. In case of one dark and one light, you can test again with morning urine at an interval of two days and if the depth gradually increases, you should be pregnant. If the test is still deep and shallow, it may be an ectopic pregnancy, which is more likely to be an ectopic pregnancy, or it may be an embryonic dysplasia. To confirm whether you are pregnant or not, you can check your blood HCG. A blood HCG value of more than 30 IU/L indicates a high possibility of pregnancy, and then you can recheck your blood HCG every other day. If there is no doubling every other day, you need to check ultrasound to rule out the possibility of ectopic pregnancy and possibly fetal abortion.
