Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Clinician counseling for implant users should involve an explanation of the likelihood of irregular bleeding and the possibility of continued or frequent bleeding throughout three years of use. If that counseling does not provide specifics of the actual distribution of bleeding patterns described in published literature, there remains the real possibility of biased or directed counseling, leading to an inaccurate and exaggerated expectation of potential bleeding changes. This study aims to evaluate if a standardized script accompanied by a visual aid regarding expected bleeding profiles, with intention to remove any possibility of negative or positive framing, could change users' expectations and satisfaction with their method, leading to lower discontinuation rates.
