By which week do pregnant women get implantation bleeding?

Implantation bleeding typically occurs around 6 to 12 days after conception, which corresponds to about 3 to 4 weeks into a woman's pregnancy. This timing aligns with when the fertilized egg attaches itself to the uterine lining. Not all women experience implantation bleeding, but for those who do, it can appear as light spotting or a small amount of blood.
