Cervical Changes in Pregnancy

The cervix is the lower segment of the uterus through which the cervical canal passes. It connects the uterine cavity and the vagina. Physiological changes occur in this organ during pregnancy. The color of the cervix becomes bluish in the first days after fertilization. This is due to the dense vascular network and abundant blood supply.

The density of the cervix changes. It becomes softer under the influence of estriol and progesterone. There is a branching of the glands of the cervix, which expand noticeably.

When Do Cervical Changes Start in Pregnancy?

The first changes in the cervix become noticeable after fertilization. The greatest physiological transformations occur in the first and last trimesters of pregnancy. The degree and nature of the changes will depend on the hormonal balance of the woman, her initial health, the weight of the child during the gestation period, and other factors.


Changes in the cervix occur in the 1-3rd week of pregnancy. The color, density, and length of this organ change. The cervix shortens as the fetus grows closer to delivery.

This change occurs at 32 weeks. The cervix begins to dilate at 36-39 weeks of gestation. Such changes indicate the beginning of delivery.

Prevention methods

Preventive measures help eliminate the likelihood of infection, inflammation, erosion, and other pathologies in the cervix. Timely prevention of beginning changes will help to better endure pregnancy. All preventive measures are best taken before pregnancy.

It is worth paying special attention to this organ during pregnancy if a woman has previously suffered from various problems with the cervix. Prevention methods:

Regular examination by a gynecologist.

It is necessary to undergo an examination on a gynecological chair at least once every six months. This is an effective preventive method that helps to detect and fix the problem in time. The doctor will prescribe a sparing or radical treatment, depending on the diagnosis.

Timely treatment of inflammation

Treatment should be started immediately if inflammation or infection is detected. This can be a provoking factor in the development of more serious diseases. These include cervical cancer. Manifestations of pain, discomfort, and other unpleasant sensations are a good reason to undergo an examination.

Cytological examinations

Recommend obligatory laboratory examination as a prevention of cervical cancer. A smear is taken for papillomavirus and other diseases. It is recommended to do this when identifying secretions of unknown etiology, the presence of pain, and bleeding. Such an examination is carried out no more than 1 time per year if there are no visible unpleasant symptoms.

Why Cervical Changes happen in Pregnancy?

Normal changes in the cervix are due to hormonal changes. Tissues become softer under the influence of progesterone and estriol. The color of the cervix changes due to increased blood flow and vascular density and becomes more saturated. There is a noticeable elongation of this organ. The length shortens as the fetus grows.

Pathological processes in the cervix have other causes. Erosion may appear due to the development of sexual infection, dysbacteriosis, or inflammatory processes. The cause can be injuries, an active sex life without protective equipment, and hormonal disorders.

More serious changes in the cervix during the gestation period may be the result of genetic causes, abortions, and advanced inflammatory processes. Such reasons can provoke the appearance of cervical cancer.


It is worth following simple rules to prevent pathological changes in the cervix during pregnancy. They are associated with hygiene, sexual life, regular check-ups, and other activities that eliminate the problem in time or prevent its occurrence. Consider the main means of protection against abnormal changes in the cervix:

Hygiene products

Do not use dry soap, products with alcohol, and with the addition of surfactants. It is better to do a regular warm shower without hygiene products or use only pharmaceutical gels approved by dermatologists and gynecologists. They should not contain allergens, toxic substances, and petroleum products.


Use barrier contraception during sexual intercourse during the gestation period. This will significantly reduce the risk of sexually transmitted diseases, inflammation, and irritation. Contraceptives are aimed not only at protecting against unwanted pregnancies. Most people forget about this.

Vaginal suppositories

It is a tool to solve an existing problem. The doctor may prescribe vaginal suppositories if cervical erosion is observed. These will most often be products made from natural ingredients with anti-inflammatory properties. You cannot use vaginal suppositories on your own. They can only be prescribed by your doctor.


The reason for going to the doctor should be a pain, bloody and other abnormal discharge, and a feeling of severe dryness or burning in the vagina. Pain during urination, itching in the area of the labia, swelling, and redness are also a reason to contact a specialist.

Consultation with a gynecologist is necessary if you experience pain during sex. Poor results of cytological studies are a good reason to undergo additional examinations.

What Not to Do

You should immediately consult a doctor if you have symptoms that worry you. Any ignoring of the problem can lead to irreversible consequences. Sometimes it’s better not to take unnecessary actions to prevent a problem. Only a doctor can analyze the situation and prescribe treatment.


Diagnosis at home is unacceptable. Treatment with non-traditional methods is prohibited. Any intervention in a woman’s body without an attending physician can be fatal to the fetus.


Abortion is not a reason for detecting cervical erosion, a sexually transmitted disease, or a viral disease. Modern medicine can treat these problems while saving the child.

Sexual activity

It is better to temporarily abstain from sexual activity when a problem with the cervix is ​​detected. This will help speed up the healing process and prevent possible consequences.
