Pap Smears/Implanon/Mirena

An intrauterine device, aka IUD, such as Mirena, is used as a lasting birth control measure to manage heavy menses. Mirena IUDs reduce the chance of getting pregnant by increasing cervical mucus, which stops fertilization of an egg by sperms and thinning the uterus lining, which decreases the amount of menstrual bleeding.
