This study is checking how women like using non-medicated intravaginal rings (IVRs). These rings are not medicine but are used inside the body to see if they are easy and comfortable to use. Women who want to join must be 18-49 years old and have been having sex with a male partner weekly for the past three months. They also need to be healthy and use a non-vaginal birth control method like pills or an IUD (a tiny device placed in the uterus to prevent pregnancy). If you are allergic to silicone or EVA (materials used in the rings), pregnant, or have certain health issues, you cannot join.

• Length of Study: Participants will be involved for at least three months.
• Visits Needed: Regular visits are required to monitor health and comfort with the rings.
• Risks: Low risk, but not suitable for those with certain allergies or infections.
