Cervical Mucus During Pregnancy in Norm and Pathology

cervical mucus during pregnancy

During pregnancy, the increased hormones secretion induces the readjustment of the whole female body. There are major transformations in the reproductive system – the size and mass of the uterus increase, the blood flow intensify, the shape and position of this organ changes. The production of cervical mucus during pregnancy is another interesting point.

Characteristics

Thirty days after the conception the cervix has already become softer, and the blood flow to it increases in intensity. By the end of pregnancy, the mechanical force of the cervical connective tissue becomes 20 times less than before the gestation period. Thus Mother Nature has alleviated the process of cervical dilatation during childbirth and the passage of the fetus through the birth canal.

Half of the cervical mass during pregnancy is occupied by the glands; their weight surpasses that of the muscle and collagen fibers. These glands are secreting cervical mucus. Since the first days after the conception, the mother’s body is sheltering the fetus from negative influence, the cervical canal is filled with mucous plug – a thick, sticky mucous mass.

Actually, the female body (the ovary) forms a new endocrine gland – the corpus luteum (or “yellow body”) which keeps functioning for 4 months, gradually transferring its functions to the placenta. Here, under the influence of chorionic gonadotropin, progesterone and estrogens are produced.servical mucus during pregnancy - vaginal discharge

During the whole course of pregnancy, the consistency of cervical mucus can vary, the number of glands is gradually increasing, and the contents of the mucus depends on the balance between estrogens and progesterone in the future mother’s organism. Under the influence of progesterone, it becomes sticky, viscous, and nontransparent, playing the part of mechanical and immune barrier against germs.

Judging by the contents and the amount of cervical mucus during pregnancy you can draw a conclusion about the hormonal balance between progesterone and estrogens in the female body. When there is not enough progesterone, the mucus becomes less viscous and more transparent.

It can have whitish or yellowish color, during colposcopy it is possible to discern its inhomogeneous structure, the presence of granules and threads. The maximal changes in the production of cervical mucus during pregnancy happen before childbirth when the mucous plug comes out of the body and the birth canal begins to prepare for the delivery of the baby.

Possible pathologies

If the cervical mucus during pregnancy is brown-colored, there is a possibility of premature birth. The increase in spotting during pregnancy and the changed color of the excreta can be a sign of an inflammatory process.cervical mucus during pregnancy - resisting germs

  • The foam-like, sticky spotting with an unpleasant odor can indicate bacterial vaginosis;
  • Clotted spotting accompanied by the vaginal itch is a sign of yeast vaginitis;
  • Watery discharge without a smell during the third trimester of pregnancy can signify the amniotic fluid leakage;
  • Brown, mucous excreta accompanied by nagging pains in the lower abdomen tell about the threat of a spontaneous abortion.

A moderate amount of the mucous, transparent discharge should always be there during pregnancy. Due to its presence, the mucous membrane is kept intact (especially during sex). The beneficial microorganisms which inhabit the vagina are able to stop germs from getting into the body and harming the growing fetus.
