Patient's question:
Doctor: First of all, thank you for seeing my question. My menstrual cycle is quite regular, 28 days. It started on December 13th and ended on the 16th. On December 23rd, I had sexual intercourse without taking any protective measures. My period was expected on January 11th, but it has not arrived yet as of the 13th. On the 12th, I used a pregnancy test and it came back negative, but I don't know much about this. Please provide an answer. Thank you!Doctor's answer:
Hello: Accuracy is over 99%! But it must be used correctly.
