If the egg is not fertilized, all the preparations that your body went through for it must be sloughed off, thus the period

As simply as I can put it, during a normal 28 day cycle, the first week is when you should have a period, week 2 is insignificant for this question, week 3 is when ovulation occurs. The egg is released into the uterus and if sex occurs the egg has a chance of fertilization. If fertilization occurs, the egg will attach itself to the uterus wall and the blood/tissue that has collected will be used to nurishe the growing embryo. If no fertilization occurs, the egg is released with the menstral flow at the beginning of the next cyle. Granted this is textbook timing and all women can vary on their exact ovulation time but this is a good example.

During the menstrual cycle of the human female, an egg can be fertilised almost any time after it is released from the ovary.
If it is fertilised - it will try to implant and then being so make hormones (chemical signals) so that the period does not happen.
If the egg does not implant properly or if there is something wrong with it, then the hormones might not be made and the period could start.
Then the cycle is reset again - and another egg begins to grow and get ready for release.

An egg is released from the ovary about 2 weeks after the period. If it is fertilized it will then implant into the uterus in about and no period will happen. If the egg is not fertilized no pregnancy occurs and the uterus will shed or give off the lining it made to take on a pregnancy and you have a period. The uterus then develops a lining again for another pregnancy and again if none occurs you have a period.

When is an egg fertilized? - when an ovum and sperm meets BEFORE and not after or during period.
Why does it happen? - every month, women starts to build up blood inside the lining of the uterus in preparation for the fertilized ovum. Once fertilized by a sperm, it embeds itself onto the blood lining in order for the fetus to thrive.
But approximately 14 days after, if no fertilization occurs, the ovum degenerates and sheds off together with the "blood" through the vagina, hence we menstruate.
Menstruating signals that we are not pregnant, at the same time it also signifies that we have the capacity to get pregnant, since no fetus can survive without the blood lining in our uterus.

No that is not correct. Every month (varies for each woman, if your regular then its every month) your body releases an egg. Your period is the way your body gets rid of the egg that it released during ovulation. The egg is fertilized after your period because a new egg is released.
