During the early stages of pregnancy, cervical mucus is typically creamy, white and odorless, according to Registered Nurse Maureen Stephens with ConceiveEasy. Pink or brown blood may become mixed with cervical mucus, which is common. By week six, the cervical mucus turns completely white as more mucus is produced within the vagina.
As the pregnancy progresses, cervical mucus becomes more slippery and eventually develops into a mucus plug and dries up almost completely, according to Stephens. Cervical changes cause the mucus to change form and structure during pregnancy. At the onset of pregnancy, the cervix moves to a lower position and becomes softer, affecting the thickness of cervical mucus.
Once a woman nears the stages of labor, the mucus plug that has accumulated may be discharged into the vagina and possess a slightly bloody, pink or clear appearance, according to WebMD. Labor typically begins one or two weeks after the mucus plug is discharged.
Women attempting to get pregnant often notice changes within cervical mucus, according to WebMD. For example, a few days after a woman's menstrual cycle, the vagina is often dry with little to no mucus. Approximately five days after her cycle, cervical mucus becomes sticky and thick, eventually turning white and thin. Approximately 10 days after a menstrual period, the cervical mucus is stretchy, slippery and clear, resembling the consistency of egg white and thickening within the next few days. The cervical mucus ultimately dries before the next menstrual cycle.
