Verified step by step guidance1
Understand the process of implantation: Implantation is the stage in pregnancy when the fertilized egg attaches to the wall of the uterus.
Recognize the timeline of early embryonic development: After fertilization, the zygote undergoes several cell divisions to become a blastocyst.
Identify the journey of the blastocyst: The blastocyst travels down the fallopian tube towards the uterus, which typically takes several days.
Learn about the timing of implantation: Implantation usually occurs when the blastocyst reaches the uterus and begins to embed itself into the uterine lining.
Note the typical timeframe for implantation: Implantation is generally complete around 10-12 days after fertilization, as the blastocyst needs time to travel and prepare for embedding.
