Fertile Cervical Mucus – Ovulation and Cervical Mucus

Fertile cervical mucus is easy to spot once you know what you’re looking for. Its a great sign of fertility, and along with other signs, you can get a good idea of what your body is doing – if you’re ovulating, if you are fertile or non-fertile.

Below are the differences between slightly fertile mucus, fertile mucus and highly fertile mucus.

Possibly Infertile or Slightly Fertile Mucus

Following infertile mucus, you may find possibly infertile or slightly fertile mucus. Mucus in this state is responding to increasing levels of oestrogen and is usually sticky and may feel damp. There is only a slight chance of conception with this form of mucus – sperm will find this mucus particularly hard to swim through.

Words which women commonly use to describe mucus at this time include:

  • Creamy
  • Pasty
  • Thick
  • Cloudy
  • Sticky
  • Flaky
  • Tacky

‘Possibly Infertile’ or ‘Slightly Fertile’ mucus still feels more dry to touch than fertile mucus. It may be yellow, white or opaque. Upon observation by touch between your thumb and index finger, you will find that it does not stretch or move, but may be damper or in more quantity.

Fertile Mucus

Fertile mucus usually signals the impending arrival of ovulation and for those who are hoping to avoid conception, you must avoid unprotected intercourse at this time. On the other hand, if you’re trying to get pregnant, this is the time where you’re more likely to conceive. Your mucus may change to a more watery state and feel more slippery. You may find this mucus is more abundant than the earlier, less fertile forms of mucus.

Words which women commonly use to describe mucus at this time include:

  • Wet
  • Slippery
  • Watery
  • Clear
  • Thin
  • Fluid

Fertile mucus feels wet and slippery compared to infertile mucus. It’s likely to be clear or have a cloudy/white colour to it. Fertile mucus will even smell sweeter (and apparently taste sweeter) than less fertile mucus which may have a more vinegar scent, however the most important observation to make is the wetness/slippery observation.

Highly Fertile Mucus

This time is the most likely time to find what is commonly known as EWCM (egg-white cervical mucus) or spinn (short for spinnbarkeit which is german for spiderweb). EWCM is ‘stringy’ hence coming from the word spiderweb. It may appear as a glob, or in smaller amounts amongst more watery mucus. Not all women have egg-white cervical mucus, so don’t be alarmed if you don’t notice any. Some women swear by Evening Primrose Oil to increase their levels of EWCM, however if you see a naturopath, they can suggest an appropriate dosage for you.

If you were to stretch EWCM between your thumb and index finger, you may notice it stretches, unlike the infertile mucus which keeps it’s shape. You can see why this form of mucus favours sperm – it has a consistency similar to sperm and creates an ideal environment for them to reach the egg.
