It can be difficult to identify cervical mucus after having intercourse, as semen and cervical mucus look very similar and share similar properties? – both cervical mucus and semen are in charge of transporting and nourishing sperm?.
However, if you examine them closely, you might be able to tell that cervical mucus, unlike semen, is clear (less white) and quite stretchy in texture. Semen will dry up more quickly on your fingertips than cervical mucus.
Much more detailed information can be found in the cervical mucus section of the website, including pages about fertile mucus, changes in mucus quality, and identifying cervical mucus.
It can be difficult to tell the difference between cervical mucus, semen, and arousal fluid?, but it is important to be able to distinguish them if you are going to be entering cervical mucus as a fertility clue?.
Arousal fluid and cervical mucus can feel similar, although arousal fluid is secreted by your vagina? and cervical mucus is produced by your cervix?. Arousal fluid can be present at any time in your cycle when you are sexually aroused, whereas the quality of cervical mucus changes during the menstrual cycle?. Arousal fluid may be felt for several hours after sexual activity – so it will be especially difficult to tell it apart from cervical mucus at this point.
Arousal fluid usually feels more watery and will not stretch as much as cervical mucus, which will stretch significantly between fingers without breaking. Arousal fluid feels slippery when rubbed between fingers but when left, it will dry up quickly on your fingertips. Arousal fluid is also soluble in water, so will dissolve if placed in water, whereas cervical mucus will form a ball and sink.

The production of cervical mucus? is at its maximum during the fertile window?. Fertile mucus feels like egg? white - it is very wet (watery), transparent and slippery. It is also very stretchy. This type of cervical mucus is usually secreted during the few days leading up to ovulation? and provides a welcoming environment for sperm?.
The quality of cervical mucus varies from woman to woman and from cycle to cycle, and it can also be affected by external factors such as stress or internal factors such as illness so it is difficult to give precise instructions as to what you should be looking for. But the more experienced you become at studying your cervical mucus, the easier it will be for you to spot any unusual patterns.
There are a number of features you can be looking out for, including:
Look - cervical mucus can be transparent, white, off-white, cream or just off-pink.
Feel - cervical mucus can feel dry, wet, or slippery.
Consistency - cervical mucus is usually quite stretchy.
You also need to check that you are not confusing cervical mucus with residual semen (see here) or arousal fluid? (see here).
