What happens in the ovary and in the blood stream in days 1-14 that bring about a change in the uterus

In day 1, the brain will produce Follicle-stimulating hormones and Luteinizing hormones. These hormones will travel through the blood stream, reach the ovaries and cause the production of egg cells. Estrogen will be produced. In the next few days, the uterus lining will regenerate. Then, the egg cell will travel to the Fallopian tube. The uterus will secrete lubrication to ready for intercourse.
