Patient's question:
I had my period on the 10th of last month, and it has been about 45 days since then. My period hasn't arrived yet, and a pregnancy test also showed negative. What could be the reason? How long after pregnancy can it be detected?Doctor's answer:
Generally, a pregnancy test can be detected about 10 to 14 days after fertilization, but some people may take longer, possibly up to 20 days. Some say pregnancy can be detected three days or even one day after conception, but here the term "pregnancy" does not refer to the time from fertilization.
