A light red color on a five-day pregnancy test paper is mostly normal. When you are five days pregnant, the HCG level in your body is low, and the HCG level in your urine is correspondingly low, so the light red color of the five-day pregnancy test paper may appear, which is mostly normal. You can wait until the hormone level in the body rises and then use the test paper to test, or you can draw blood to check the HCG changes in the blood, in order to clarify whether the hormone level is normal. It is recommended that women should maintain a happy mood, exercise properly and eat more food rich in protein and folic acid to facilitate the growth and development of the fetus after finding out that they are pregnant. If women experience abdominal pain and other symptoms during this period, it is recommended that they consult a doctor in a timely manner, under the guidance of the doctor, to complete the relevant examinations, to clarify the cause of the disease, and to target the treatment.
