The side effects of using the ring are: number one – some people (although rare) have some discomfort with the placement if they’re not comfortable with their body and comfortable actually placing it. Some people do not have the comfort level of actually inserting something in their vagina. In addition, they also can have irregular bleeding – as any form of birth control can do that occasionally. Most people do not have the problem of it falling out and it does not have to be removed with intercourse. However, on occasion there are people that have some difficulty due to their elasticity in their vagina in maintaining the vaginal ring.
