The cervix produces a protective lubricant
that is commonly termed, cervical mucus. This mucus changes slightly in colour,
amount and texture throughout your cycle and is completely normal!
By normal I mean that it is a healthy
representation of the secretions from the cervix (just a fancy name for the
opening of your uterus) that fluctuate with changing hormone levels.
What is its purpose?
To protect and moisten the lining of your
cervix and vagina. All the mucus membranes that make up the barrier between the
external world and your body are lined with a fluid; the mucus membranes in
your mouth are protected by saliva, your ears have wax, your nose has, well, more mucus!
Cervical mucus produced during the
“infertile phase” of your cycle has another protective role, it creates a plug
over the opening of the uterus, which apart from stopping nasties such as germs
and dirt from getting up into the uterus and causing infection, it also stops
sperm from being able to enter the uterus.
Imagine it is like a natural
diaphragm! But not only is this natural diaphragm a barrier, it has an acidic
pH that acts as a spermicide, rendering those little guys completely useless!
Cervical mucus produced during the “fertile
phase” of your cycle however, is completely the opposite! It is more basic
(alkaline) and therefore dissolves the acidic plug, exposing the entry point to
the uterus and allowing the passage of sperm towards the egg.
It is much more
fluid and slippery, which sperm love! They wriggle their tails around, exactly
like a tadpole and within as little as 30 minutes can have swam up though the
vagina, uterus and down a fallopian tube to fertilise a waiting egg!
What are the different types?
Basically when I teach my patients and NNP
clients to recognise the different types of cervical mucus I break it down into
4 categories:
Infertile Cervical Mucus: As detailed above
this mucus acts as a natural diaphragm and spermicide. It is usually thick,
white, pasty and unchanging in amount. Some women describe it as UHU (the glue
stick!) as it can be sticky and tacky, and dries as a white crust on your
underwear.
You may notice this type of mucus in the couple
of days after your period has finished and again after ovulation has occurred
(see the green petals in the diagram).
Possibly Fertile Cervical Mucus: This mucus
is the “change-over” mucus, it varies greatly for different women ranging from
clear, thin and watery to creamy white and lumpy.
Remember, every woman is
different and when you learn the NNP technique you are learning how to read your
individual pattern of fertility.
This mucus only lasts 2-6 days in the lead up
the ovulation (see the orange petals)
Fertile and Very Fertile Cervical Mucus:
These cervical mucus types should be treated with the utmost reverence!
For
those who are wishing to fall pregnant it is the most desirable and exciting
cervical mucus to discover.
But for those who are practicing the NNP technique it is a dangerous couple of days when barrier methods should be
employed.
This type of cervical
mucus is profuse, wet, slippery and may even be stretchy like egg-white. It is
short lasting, from a couple of hours to 3 days (See the red petals on the
diagram).
What about when you are on the pill?
Just as women taking the pill or any other
synthetic hormonal contraception do not get periods because they are not
ovulating (they simply have a what is called a withdrawal bleed) they also do
not get fluctuations in cervical mucus types.
A woman taking synthetic hormones
will only experience one type of cervical mucus, and that is the Infertile
type.
Would you like to learn how to use this knowledge to prevent or facilitate pregnancy?
All NNP Programs teach:
- How to achieve contraception though
monitoring changes in cervical mucus.
- More detail about the cervical mucus types.
- When you must use protection if you are
interested in contraception (or when to have lots of sex if you want to have
babies!)
- How to recognise hormonal imbalances such as low levels of cervical mucus. This can be remedied easily with herbs, nutrients and/or diet and lifestyle changes.
The NNP technique also employs Basal Body Temperature (BBT) recording and Lunar Phase Fertility for maximum protection.
