Patient's question:
Can pregnancy be detected after implantation?Doctor's answer:
After implantation, pregnancy cannot be detected. The time it takes for sperm to fertilize an egg is approximately 24 to 48 hours. After fertilization, the zygote travels through the fallopian tube to the uterus, and the implantation process takes about a week. Therefore, it is generally necessary to wait at least eleven days after intercourse before using a highly sensitive early pregnancy test. Additionally, a pregnancy test can be detected seven days after a delayed menstrual cycle. Two red lines on the test paper indicate a positive result, meaning pregnancy. Ten days after sexual intercourse, blood HCG testing can confirm early pregnancy diagnosis, which is currently the earliest and most accurate method.
