Summary
This phase 3 trial is testing whether a levonorgestrel vaginal ring, worn continuously for 28 days, can effectively prevent pregnancy in females aged 13 to 45 who are sexually active and able to conceive. Researchers will track pregnancies and side effects over about 13 months of use. The goal is to see if this monthly ring offers a safe and reliable contraceptive option.
