Patient's question:
My girlfriend had her period on November 5th. We had sexual intercourse on the 15th and 16th, and she took emergency contraception on the morning of the 17th. Today is December 10th, and she still hasn't had her period. Could she be pregnant? Please tell me what to do. (After taking the emergency contraception, she ate several bananas, and she also took some cold medicine a while ago. Could these medications interact with the emergency contraception, making it ineffective?) We are very worried. Please help us! Thank you!!!Doctor's answer:
Generally, without contraception during sexual activity, there is a possibility of pregnancy if the menstrual period is delayed. It is recommended to use a pregnancy test strip 7 days after the menstrual cycle is delayed, as the test paper will show two red lines indicating a positive result, which means pregnancy. Additionally, 10 days after sexual activity, you can go to the hospital for a blood HCG test, which is the most accurate method for detecting pregnancy.
