• Some women feel a light tension in the breasts.

• Sometimes a little pain can be felt at the left or right ovary. This is caused by an increased blood flow to the ovaries and an involuntary contraction of the ligaments that pulls the ovary closer to the fallopian tube (which allows easier passage for the released egg into the tube).

• The cervical mucus becomes much more abundant (usually 10 to 14 days into a normal 28 day cycle).  This creates an ideal medium for the spermatozoa to swim in.

There are two much more accurate methods of knowing the date of ovulation:

The temperature method:

At the day of ovulation, the temperature increases to the region of 37.2° to 37.3°.

The only problem with this method is that the temperature needs to be taken very regularly under similar conditions to be sure of the slight change.

The testing method:

The second method to know the day of ovulation is a simple ovulation test that can be found at your local pharmacy. 

This test measures the level of the LH hormone (Leutenising Hormone) in the urine.  It is normally advised that this test be taken each day from the 11th day of the cycle until a milky-blue appears in the test (the colour may change depending on the manufacturer).

This is a very reliable test and gives about 98% accuracy for the date of ovulation.
