Can you accurately predict the most fertile days of the month? Is there one predictor that works for every woman? To begin with there are as many unique menstrual cycles as there are women in this world (and there are lots of them). Its not an exact science but there are techniques to identify the most fertile time in the female fertility cycle.

The most common mistake that women make in estimating fertile days is to think that ovulation always occurs 14 days after the last day of your period. This is not true as the monthly cycles differ from woman to woman. Your body is also in constant change from month to month.

How can you tell your most fertile days of the month?

• 
  The most fertile days of the month occur when you ovulate. Ovulation is when one or more eggs are released from one of your ovaries. An egg survives only 24 hours after ovulation. However, sperm can survive about 3-7 days. You therefore have about 4-5 most fertile days of the month.
  

• 
  Your period normally comes about 12 -16 days after ovulation. Therefore, in the average 28 day cycle (the first day of menstruation being day one) ovulation takes place around day 13 to 15. These are the most fertile days of the month. The least likely time to conceive is from day one to day seven.
  

• 
  The length of a normal menstrual cycle however varies between 23 and 35 days. Ovulation could therefore occur earlier or later in your cycle. The most important thing to remember is that the egg is produced about 12-16 days before the next period starts. So there's always a bit of estimation involved.
  

However there are many different ways to predict ovulation and determine your most fertile days of the month. Some are more accurate than others. Once you are in tune with your body, you can easily tell which changes signify the onset of ovulation and take full advantage of these fertile days.
