Patient's question:

15 hasn't arrived yet, postponed by three days, no contraceptive measures taken, is it possible to be pregnant? Previous treatment history and effectiveness: Never had this kind of experience What kind of help do you want: Want to know if you are pregnant

Doctor's answer:

Hello: There are many reasons that can cause a delayed menstrual period, such as birth control pills, pregnancy, gynecological diseases, endocrine disorders, and so on. Normally, if the menstrual period is one week earlier or later, it is considered normal. Since yours has only been delayed by three days, it might come soon. If you take a blood test, pregnancy can be detected 10 days after intercourse. Around one week after the delay, you can use a pregnancy test kit. You can wait a few more days to see if it arrives, or check if there are other reasons for the delay.
Based on your situation, it is recommended to have a blood HCG test at a regular hospital if the menstrual period is delayed by 10 days to confirm the diagnosis.
