Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This is a randomized, controlled trial investigating whether immediate versus standard, "Sunday Start", initiation of transdermal hormonal contraception (the patch) in post-abortion subjects can improve compliance and the continuation of contraception. Immediate initiation of the patch has been studied in women seeking contraception when they are not immediately post-abortion, and this "Quick Start" method has been shown to improve the continuation of the patch into a second month. The primary hypothesis of this study is that immediate initiation of the patch in post-abortal women will improve the continuation of contraception over delayed initiation on the first Sunday after an abortion.
