How can the test strip turn into two lines?

Patient's question:

No

Doctor's answer:

Hello, this situation is considered weakly positive, which means pregnancy. It is more accurate to recheck after one week. Regular prenatal examinations should be conducted after pregnancy, such as ultrasound for fetal anomaly screening and Down syndrome screening, etc. Calcium supplements should be taken regularly in the late pregnancy to prevent calcium deficiency in the fetus and the mother.
