If the color of the 2nd line of the early pregnancy test is light, it is considered to be caused by the short duration of pregnancy. There are also some abnormal pregnancy conditions that can lead to this state, such as ectopic pregnancy, biochemical pregnancy, etc. If the patient has no other discomfort at the moment, she can use the morning urine test again after 2-3 days, but if there is a combination of abdominal pain and vaginal bleeding, she needs to be alerted to the occurrence of abnormal pregnancy and needs to be further examined. There are also some medications and other conditions that may cause a weak positive pregnancy test and need to be further reviewed.
