Patient's question:
I have had sexual intercourse with my boyfriend, but my period hasn't come. It was supposed to arrive on November 20th, but it has been delayed until now. I have a history of irregular periods.The sexual activity occurred on November 5th, and I took a self-test in the morning on November 25th, which was negative.
I would like to ask, how long after sexual intercourse can pregnancy be detected?
Doctor's answer:
Test strips require 14 days after sexual activity to be accurate. It is best to use morning urine for testing. Blood HCG tests are recommended at least one week after sexual activity to determine pregnancy.Early pregnancy symptoms include missed periods, breast tenderness, swelling, and itching, nausea and vomiting, and frequent urination. Other early pregnancy symptoms include: skin color changes—such as darkening of the skin or the appearance of stretch marks on the abdomen, especially more noticeable in the later stages of pregnancy. Vaginal mucosa discoloration—during early pregnancy, the vaginal mucosa may appear darker due to congestion. Easy fatigue—fatigue is common in early pregnancy, often accompanied by a strong desire to sleep.
