Our study is testing an investigational vaginal ring that is not on the market. The ring is designed to deliver continuous low dose estrogen and progestin. We are testing the ring to find out how effective it is at preventing pregnancy and to learn more about side effects and bleeding patterns during ring use.
This study will enroll 250 women at 10 different sites across the United States to test an investigational copper IUD that is not yet on the market. We are testing the IUD to find out how well it prevents pregnancy.
