What Does Pregnancy Implantation Mean?

The Uterus Prepares
Once the follicle in your ovary, called the corpus luteum, releases the egg, it will begin to release progesterone. This hormone signals that your uterine lining needs to thicken to prepare for implantation. This process (called “endometrium”) occurs during a period of 12 to 16 days.

Finding a New Home

As soon as the blastocyst exits the fallopian tube, it will burrow into the uterine lining. The trophoblast, which surrounds the embryo, will dissolve the endometrium lining, and later form the placenta. As the trophoblast burrows deeper into the endometrium lining, it envelopes the mothers blood vessels, and they are diverted into the trophoblast structure.

The trophoblast will continue to grow larger, as will the embryo within; it will continue burrowing until the entire structure is enveloped by the surrounding endometrium lining. The endometrium lining will become the embryos new home, as the embryo develops.

    I have taken a few upper level biology classes, and it seemed very clinical. It seemed more like a professional happening, and less the family / family matter.
