Patient's question:
My period is a week late and I haven't gotten it yet. I'm worried I might be pregnant. I've been experiencing lower back pain, abdominal pain, and breast tenderness. I bought a pregnancy test kit and followed the instructions to use it. I took the test twice, and both times it showed one line, indicating a negative result, meaning I'm not pregnant. However, my period still hasn't come, and I can't remember the timing of my last sexual intercourse.What kind of help do I need: What is the accuracy rate of pregnancy test kits?
Doctor's answer:
Analysis of the condition: The menstrual cycle of a woman is generally 28 to 30 days. It is still within the normal range if it is advanced or delayed by about 7 days, and the length of the cycle varies from person to person. However, if menstruation does not occur after more than 7 days, it is considered delayed menstruation. If your test method is correct and the product itself is not defective, the accuracy of the pregnancy test strip is approximately 85% to 95%. The earliest time to use a pregnancy test strip is 6 days after intercourse. For more accurate results, wait until 11 days later, as that is when it is more reliable.
