Pregnancy: Implantation of the fertilized egg occurs between 6 and 8 days after conception so the bleeding she had is probably too soon for implantation bleeding. She apparently then had a period and this would argue against her being pregnant. However, sperm can live in her body for up to 5 days and pregnancy can occur anytime during the menstrual cycle.
