What Happens to the Cervix During Pregnancy?
During pregnancy, several changes occur in the cervix, the structure between the vagina and uterus. Every pregnancy is slightly different and women may experience these changes at different rates. In the cervix during pregnancy, a mucus plug will form as the cervix thickens, and towards the end of the pregnancy, the cervix will thin and dilate, allowing the mucous plug to fall out so the baby can be delivered. These changes occur in concert with a number of other physical changes associated with the pregnancy. The first change seen in the cervix during pregnancy is thickening as the cervix begins producing more glandular cells. These cells exude mucus, forming the mucus plug that will keep the uterus securely sealed during the pregnancy. The thickness achieved will vary from patient to patient. The cervix can also appear red or inflamed during examinations, and sometimes some breakthrough bleeding or spotting will occur.
