This is known as the menstrual cycle.
The first day of menstrual bleeding is the first day of the menstrual cycle, The day before that is the last. The menstrual cycle is usually about 28 days long It can be longer or shorter depending on the individual. In any case we will work with a 28 day cycle here. Ovulation usually happens 1/2 way into the cycle that is 14 days. At this time an Ovum is released via the oviducts and can come in contact with sperm that is ejaculated by the male and be fertilized. The fertilized ovum will then make its way to the wall of the uterus and implant itself into a specialy prepared lining and then begin to develop a baby. If the ovum is not fertilized it will break up after about two days which will activate hormones that will cause the lining on the uterus to start falling away. When thisstarts to happen you get menstrual bleeding. Menstrual bleeding usually lasts for about 3 to 7 days and when done a new lining is created on the uterus in preparation for the next fertilized ovum. Remember though if you use this information to avoid becoming pregnant Thet sperm can remain alive within the uterus for about 4 days so even if ovulation has not occurred yet having sex 4 days before can lead to pregnancy. So the period in which to avoid unprotected sex in a normal 28 day cycle would be days 9 to days 17.

One of the methods to predict ovulation is calendar method. You just check you menstrual cycle and calculate ovulation. e.g. If you have a 28-day cycle, ovulation starts around the 14th day of the menstrual cycle. I use this calendar http://www.ladys-calendar.com. and it helps me to know days of ovulation.
