A coleta dos dados ocorreu por meio de um hist\u00f3rico retrospectivo di\u00e1rio sobre o uso de m\u00e9todos nos 30 dias antes e ap\u00f3s o uso da anticoncep\u00e7\u00e3o de emerg\u00eancia, com 2.051 usu\u00e1rias de unidades b\u00e1sicas de sa\u00fade de S\u00e3o Paulo, Aracaju (Sergipe) e Cuiab\u00e1 (Mato Grosso), Brasil. Resultados do estudo revelaram que, em m\u00e9dia, as mulheres iniciaram o uso do m\u00e9todo 7,6 dias (DP = 2,4) ap\u00f3s o uso da anticoncep\u00e7\u00e3o de emerg\u00eancia e a descontinuidade ocorreu 17,1 dias (DP = 7,0) ap\u00f3s o uso da mesma. A maioria das mulheres utilizou um m\u00e9todo de forma cont\u00ednua 30 dias antes (44,4%) e 30 dias ap\u00f3s (65,7%) a anticoncep\u00e7\u00e3o de emerg\u00eancia. Foi identificado que apenas 8,1% das mulheres que n\u00e3o utilizavam m\u00e9todo antes da anticoncep\u00e7\u00e3o de emerg\u00eancia, usaram ap\u00f3s o seu uso (bridging). Ter 35 ou mais anos de idade (OR = 1,8; IC95%: 1,4-2,6) associou-se com o uso de m\u00e9todos contraceptivos ap\u00f3s a utiliza\u00e7\u00e3o da anticoncep\u00e7\u00e3o de emerg\u00eancia, entre mulheres que n\u00e3o usavam m\u00e9todos. Residir em Aracaju (OR = 0,7; IC95%: 0,4-0,9), associou-se negativamente. Concluiu-se que uma \u00ednfima parte das mulheres que n\u00e3o utilizava m\u00e9todo anticoncepcional algum antes da anticoncep\u00e7\u00e3o de emerg\u00eancia, iniciaram o uso ap\u00f3s o uso desta
