Ovulation occurs during the menstrual cycle of a female, in all species .This happens between the ages of 12 to 45 (ages could vary) in humans. During this process the mature follicles that are released by the ovaries, rupture. These discharge an ovum or egg. This egg participates in the reproduction process. In human females it happens around the 14th day of a twenty –eight day cycle. This is the time the female is most fertile and when having sexual intercourse during this time, it will usually lead to a pregnancy. In case you do not want a pregnancy to occur, you should consider an Over The Counter contraceptive device or the natural method i.e. using an ovulation calendar.

There are various methods of natural contraception .One such method is by using an ovulation calendar. No contraception method is full proof and 100% safe so you should know, there is always that 1% chance of failing. Tracking ovulation along with any other method is a better way to prevent a pregnancy. This method is more effective if the woman has a regular menstrual cycle and the ovulation is happening on the correct day.

By using this process you not only can time the pregnancy but also prevent one. This calendar can be got online such as at sites like ours. Just fill up the correct details and it will predict the days you will ovulate in the coming months. There are many types of ovulation calendars. Some calendars show ‘possible’ fertile days and the ‘most’ fertile days .These will be marked in different colors. This is an all natural method to know the time of ovulation. Another name for this is “Rhythm Method.” It is one of the oldest forms of contraception known to man.

This ovulation calendar does take into account the possible variations in the menstrual cycle but as with any type of contraception, there is no 100% guarantee. There are many factors that can cause changes in the menstrual cycle. The length of the cycle and time of ovulation can fluctuate every month. Some major factors that cause this to happen are stress, an illness or faulty diet etc. In case of a medical problem, its better to get it treated by a professional and then follow this method.

If you want the fertility chart that the calendar generates to be accurate, you will have to keep the program up-to-date with the latest information about that menstrual cycle. It is possible to further reduce the chance of a pregnancy by combining any other method of contraception along with the calendar. Methods like use of a condom, spermicidal jelly or foam, or using a diaphragm would also help in contraception.

This method of using the ovulation calendar is best suited to married women or those in a committed long term relationship. Although it’s not full proof it’s quite reliable and it’s free and there will be no side effects! You can make this calendar work for you once you understand how to count the day on which ovulation might occur.
