Most vaginal discharge with no itching or other worrisome symptoms is caused by natural shifts in a woman’s body during her monthly cycle. During ovulation and right before menstruation begins, discharge is often more noticeable. Just after menstruation and for several days following ovulation, a woman is typically drier. Women also commonly experience heavy discharge during periods of sexual arousal, as well as during pregnancy.
Vaginal discharge may take on many forms, depending on hormone levels. These levels often fluctuate during various times during a woman’s menstrual cycle. Most discharge originates in the cervix, which is a funnel-shaped structure separating the vagina from the uterus. Vaginal discharge with no itching, odor, or discoloration is typically considered normal.
One potential cause of vaginal discharge with no odor is ovulation. This is the period of a woman’s cycle in which an egg is released by one of the ovaries in preparation for fertilization and potential pregnancy. During this time, the cervix produces high quantities of a slippery, stretchy, clear fluid. The consistency of this fertile mucus is often compared to egg whites, although some women may have thicker or more watery discharge than others. Its purpose is to protect and aid sperm as they travel into the birth canal in search of the egg.
Pregnancy may also lead to an increase in normal vaginal discharge with no itching. This is caused both by hormonal factors, as well as the cervical mucus “plug” which forms to block off entrance to the uterus. This plug may break down and begin exiting the body weeks or even months before delivery. It generally continuously regenerates itself throughout pregnancy when this occurs.
Discharge may also increase just before menstruation due to hormonal changes, and it may continue for a day or so after it ends. Some women may have continuous vaginal discharge with no itching throughout their cycles, while others may not have any during certain days or weeks. If discharge suddenly increases, even if no other symptoms are present, it is best to speak with a medical professional.
Any vaginal discharge which is accompanied by itching, redness, pain, or irritation may be indicative of a medical condition. Discharge which is yellow, green, foamy, clumpy, or malodorous is also reason for concern. Sexually transmitted diseases are common causes for abnormal discharge, as well as bacterial and yeast infections. Normal discharge accompanied by pain or itching should always be checked out, although sometimes irritation can be caused by the moisture itself rather than any underlying condition.
