1-12. IMPLANTATION

While these cell divisions are taking place, the zygote is traveling along thefallopian tube.

The zygote reaches the uterus in about three to four days, implanting itself in the uterine lining. This implantation, the embedding of the fertilized ovum in the lining of the uterus, has taken place about seven days after the ovum was fertilized.
