During the first week after conception, your baby begins as a tiny cluster of rapidly dividing cells. After fertilization, the zygote travels through the fallopian tube toward the uterus, developing into a structure called a blastocyst. This early stage is crucial for implantation and future growth.
Though microscopic, important biological processes are already shaping early development. Hormonal changes also begin preparing the body to support pregnancy. Understanding these early stages helps explain how pregnancy develops week by week. Certain reproductive conditions, such as Implantation Failure, can sometimes affect this critical phase of development.
