Cervical Mucus Before Period. Six Stages of Production of Cervical Mucus

Vaginal secrete discharges throughout the whole menstrual cycle. Bloody secrete is followed by a few days of scant discharge. Eventually the amount of this discharge increases, while the consistency starts to thin down. The peak of cervical mucus production coincides with ovulation. Cervical mucus immediately before period is produced in average quantity, it is thick and white. Normally it should not have any specific smell and foreign matters. Presence of blood in cervical mucus between periods should serve ground for clinical examination.

The female reproductive system has a complex structure, which is constantly updating. Regeneration processes are included in the menstrual cycle (MC), which consists of three ovarian phases and three stages of endometrial alteration, correlated to them.

The female reproductive system has a complex structure, which is constantly updating. Regeneration processes are included in the menstrual cycle (MC), which consists of three ovarian phases and three stages of endometrial alteration, correlated to them.

The follicular stage of ovaries coincides with the period. That is to say, during the maturation of the ovum, the endometrial lining, which has been proliferated in the precious cycle, starts casting off. Vaginal discharge is produced even after the period is over, however it is already more mucous, rather than bloody. In this very stage cervical mucus also takes part in the updating process – removing the exfoliated cells of endometrium (inner epithelium) of the uterine cervix and the vagina. Besides, the mucus, produced by cervical glands performs a protective function, mechanically preventing the advancement of any growing infections (i.e. travelling of bacteria from the vagina to the uterus).

During the ovulation phase, secretion of mucus intensifies, which has to do with the necessity of realizing another function – creation of favorable conditions for conception.

The lutein phase of ovaries coincides with the secrete stage in the endometrium. The latter involves active preparation of the uterine mucous lining for the possible pregnancy. The endometrial layer thickens and accumulates nutritive substances. In case the prepared mucous lining appears out of use, its upper layer dies away and starts casting off. Thus, the cycle will be accomplished, reoccurring in the menstrual phase.

Stages of mucous discharge between periods

So, transparent whitish discharge is a normal form of vaginal secrete, produced throughout the whole cycle. Its consistency may change depending on a specific stage of production. We can highlight six such stages:

  1. «Dry days» – the phase, which closely follows the period and lasts for no more than 3 days. It is some kind of a rest period in the operation of mucous glands. There is almost no mucus produced in this phase, since conceiving is theoretically impossible.
  2. Thick, sticky discharge also lasts 3-4 days and points to the low level of estrogen and thus, to the fact that ovulation is not too close.
  3. Mucus between periods acquires cream-like consistency, which indicates to the imminence of the second phase of the MC.
  4. Profuse watery discharge is observed for another 2-3 days in the setting of intensive estrogen activity.
  5. This type coincides with the ovulation phase. The mucus is produced in significant amounts, it is transparent and stretches well, resembling an egg white.
  6. Cervical mucus immediately before period is rather thick, there is not too much of it, it has white color and no smell. These features are conditioned by the influence of progesterone in the endometrial secretory phase. This stage of cervical mucus is the most long-lasting one and it constitutes almost half of the whole MC.

Pathological discharge

The following changes in cervical mucus require reference to a doctor and subsequent diagnostics:

  • Discharge that has acute unpleasant smell and a different coloring;
  • Curdy structure of discharge;
  • Foaminess;
  • Massive watery discharge;
  • Presence of matter or blood in the cervical mucus.

Bloody discharge is especially dangerous in pregnant women. Even asymptomatic cases of spotting in this period require immediate hospitalization.
