The first-trimester scan is usually done between 8 to 12 weeks of pregnancy to confirm the dates of your pregnancy. Apart from dating the pregnancy, during this the scan the doctors also look for the location of the pregnancy.  In some women, the fertilized egg instead of getting implanted in the wall of the uterus may get implanted in one of the fallopian tubes which connect the ovary to the uterus.
