When produced naturally, progesterone&amp;nbsp;renders the endometrium suitable for implanting of a fertilized ovum and inhibits further release of GRH, FSH, and LH so regulates cycle and ovulation.If no fertilization take place the&amp;nbsp;corpus luteum regresses and progestrone levels drop so the&amp;nbsp;endometrium can not be maintained and menstruation occurs.&amp;nbsp;Lack of progestrone also means the clamp on GRH, FSH and LH secretion is released.&amp;nbsp; <br /> <br /> The progesterone only pill is mainly effective due to it's effect on cervical mucus, it doesnt actually stop ovulation.&amp;nbsp; <br /> <br /> If taken regularly it can cause irregular periods and it is considered less effective than the combined pill.&amp;nbsp; <br /> <br /> It is said to have a number of side effects including:&amp;nbsp; <br /> <br /> *weight gain <br /> *mild nausea&amp;nbsp; <br /> *skin changes e.g. acne <br /> *blood clots <br /> *depression <br /> *cancer<br /> <br /> &lt;br&gt;&lt;br&gt;</div>
