Learn to Recognise the Signs of Beginning Fertility
The fertile phase of the cycle begins when the ovaries start to produce oestrogen
as the egg develops. This hormone stimulates the cervix to produce different kinds
of mucus. A change in the sensation and appearance of the mucus at the vulva is
nature’s way of letting you know that you are now potentially fertile.
One of the types of mucus produced by the
cervix dissolves the mucus plug. This means that
sperm can now enter the uterus. Another type
of mucus acts as a filter, destroying unsuitable
sperm cells. Yet another type of mucus forms
channels which help the sperm travel through
your reproductive system to meet and fertilise the
egg. This mucus also protects and nourishes the
sperm, helping them to live up to 5 days.
As the ovaries produce increasing amounts of
oestrogen you will notice a changing pattern
of mucus and a difference in the sensation the
mucus produces. The mucus becomes progressively wetter and then slippery. You may
notice the mucus becomes thinner and clearer. But even if you don’t see any mucus,
the sensation of slipperiness means that you are fertile.

Every woman is an
individual with her own
individual pattern of
cervical mucus. And
her unique pattern is
a remarkably accurate
reflection of her
reproductive hormones.
