In order for fertilization to take place, there must be an egg available to be fertilized. So, fertilization can take place between an egg being released, travelling down the fallopian tube, and arriving at the uterus. Once an egg arrives at the uterus, if it is not fertilized, then the body takes steps to get rid of it (menstruation). It only takes a few days for the egg to get to the uterus after being released, so those few days are the only ones when the egg can be fertilized.
There are many reasons why land animals use internal fertilization. One very important reasons land animals use internal fertilization is protection.

basal stem cells.
The endometrium begins to form shortly after the fertilized egg (blastocyst) implants into the uterine wall (endometrium). This typically occurs 3-4 days after fertilization. After implantation, the endometrium is called the Decidua, and basalis is the portion directly under the blastocyst. The Basalis joins the chorionic villi to make the placenta.
