Can I use a test strip if my period is 7 days late?

Patient's question:

No

Doctor's answer:

Menstruation can be affected by changes in spirit, psychology, emotions, medication, environment, and nutritional status, leading to menstrual disorders. A delay or advancement of one week in menstruation is considered normal. Based on your description, it is recommended that you promptly visit a regular hospital for blood HCG or ultrasound tests. Under the guidance of a doctor, take appropriate measures and symptomatic treatment.
