You are absolutely correct!!! Ovulation and menstruation are two processes in the female body that are related, but serve different needs. Ovulation is the process by which the ovary ejects an ovum (egg) through the ovary wall. The ovum lands in the attached fallopian tube, and starts the journey down teh fallopian tube towards the uterus. If the ovum is fertilized by a sperm, it will happen in the fallopian tube. The fertilized ovum (now called a zygote) will continue down the fallopian tube, eventually reach the uterus, and implant itself in the network of blood vessels, known as the placenta, in the uterine wall. When this implantation occurs, the woman is officially pregnant.
If no pregnancy occurs, the environment of the uterus must be cleansed and properly set up again, all in hopes of receiving a fertilized ovum to nurture. That is what menstruation is all about, the discharge of the placenta, the cleansing of the uterine wall, and the reestablishment of an environment conducive to the development of a developing embryo. Typical cycle periods are around 28 days. After the menstrual cycle has occured, it takes about 7 days to reestablish the lining in the uterine wall. The next 14 days are prime reception time for a developing embryo to implant itself. If no implantation takes place, the female's body secretes a hormone designed to "flush" the contents of the uterus. This typically lasts 4 to 7 days
