The study’s objectives were to estimate the occurrence of bridging, that is, the degree to which women that had not been using contraceptive methods began to use them in the month following the use of emergency contraception, and to estimate the rates of contraceptive discontinuity before and after the use of emergency contraception. Data collection occurred through a retrospective daily history on the use of methods in the 30 days before and after the use of emergency contraception, with 2,051 users of primary health care units in São Paulo, Aracaju (Sergipe), and Cuiabá (Mato Grosso), Brazil. The study’s results showed that on average, women began their use of the method 7.6 days (SD = 2.4) after the use of emergency contraception, and that discontinuity occurred 17.1 days (SD = 7.0) after its use. Most of the women used the method continuously 30 days before (44.4%) and 30 days after (65.7%) emergency contraception. Only 8.1% of the women who had not been using the method before emergency contraception used it afterwards (bridging). Age 35 years or older (OR = 1.8; 95%CI: 1.4-2.6) was associated with the use of contraceptive methods after the use of emergency contraception among women who had not been using methods before. Residence in Aracaju (OR = 0.7; 95%CI: 0.4-0.9) showed an inverse association. In conclusion, a negligible portion of women who had not been using contraceptive methods before emergency contraception began using them afterwards (bridging).
