Cooper Surgical Ring Pessary with Incontinence Knob for Stress Incontinence

When women are pregnant they are more likely to leak urine which can severely affect their quality of life. This problem could be fixed by using a pessary. A pessary is a silicone ring that goes into the vagina which can stop or improve urinary leakage. These devices have been safely used for hundreds of years. However, pessaries has not been studied for urinary leakage in pregnancy. The investigators would like to compare severity of urinary leakage using a number of questionnaires during the last 3 months of pregnancy for women using a pessary versus women without a pessary.
