Study Summary

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.

Primary Outcome

Based subjects' self-reported ability to cope with various changes in bleeding patterns, and other demographic information, we will analyze whether an association exists between those who discontinue their method use early due to troublesome bleeding and the counseling they received on the day of method insertion.
