Clear Discharge Before Period: Functions and What it Looks Like

Clear discharge before period – constitutes a norm. Its main component is cervical mucus. The structure and external look of discharge varied depending on the stage of its production. Due to its unique composition, vaginal discharge performs two functions – protective and auxiliary, at fertilization.

Between periods vaginal discharge appears as a mixture of cervical mucus, exfoliated endothelial cells (inner vaginal lining) and bacteria, providing for normal vaginal micro flora. It does not smell and has rather high acid content. Acidity is one of the factors, providing for the performance of the most important function of vaginal discharge, namely prevention of penetration and development of infectious agents.

Some details about the functions of clear discharge between periods

So, how is the preventive function of vaginal discharge performed? First of all, as it has been mentioned before, low content of рН creates an obstacle for the survival of harmful germs, which prevents the travelling of bacteria higher in the female organism.

However, the main purpose of the basic component of vaginal discharge – cervical mucus, is:

  • Filtering most competent sperm cells;
  • Creation of optimal conditions for the sperms cells to comfortably await for the emergence of the ovum from the follicle;
  • Provide for successful fertilization.

This primary goal is achieved thanks to the characteristic features of consistency and biochemical composition of mucus, which are regulated by such hormones as estrogen and progesterone. The mucus production process has a cyclic nature.

What are the differences of clear vaginal discharge before periods depending on the stage of cervical mucus production?

Immediately after the period, during a few days, there is almost no mucus secreted – thus, the so-called “dry days” are observed. Further, thick and sticky semitransparent discharge shows up. Its consistency is conditioned by low level of estrogen in blood for more than a week before ovulation, and therefore, there is no need in production of “fertile” mucus.

The discharge looks different once the estrogen level starts to rise. Its production intensifies and the mucus thins down. At the peak of ovulation, i.e. 2 weeks prior to periods, the amount of clear vaginal discharge increases and it stretches well between fingers. Its consistency resembles that of an egg white, which is caused by strong estrogen influence. This very hormone also effects the content of discharge, which is now oversaturated with acids.

Once ovulation is over and up to the period, the women may observe thickening of clear vaginal discharge, which transforms into a thick whitish substance. Biochemical components of mucus are also different at this point. Under the influence of progesterone, which “takes up” the prevailing role, the amount of acid compounds reduces drastically. There is actually no necessity in too much mucus, since all the reproductive recourses are aimed at the preparation of endometrial lining to possible conception, and thus, vaginal discharge is produced in moderate amounts.

Disturbance of transparency of vaginal discharge

Presence of pathological admixturesin discharge, appearing in the form of blood and matter, as well as excessive thickening (curdy mass) or thinning down (profuse watery discharge) are caused by various types of diseases. Appearance of unpleasant, for example acid (may point to candidasis) or “fish-like” (vaginal dysbacteriosis) smell in clear discharge before period is an important diagnostic indicator. Any of these symptoms, as well as itching and burning, require further clinical examination.
