Patient's question:
Half a month ago, my wife and I had unprotected sex, and I came inside. It has been fifteen days now. How long should I wait to use a pregnancy test?Doctor's answer:
Generally, 6-7 days after fertilization, the fertilized egg travels to the uterine cavity for implantation. The blood hCG in the body has already started to decline, and about a week later, a urine pregnancy test will be positive. This means that two weeks after intercourse, you can use a pregnancy test strip to check for pregnancy. At first, it may be a weak positive, but it will change to a strong positive in a few days. Usually, after inserting it, it takes about one minute for the test to show two lines, which indicates pregnancy. If it appears again after a long time, it may not necessarily mean pregnancy.
