Key Clinical MessageOvarian pregnancy is one of the rarest types of extrauterine pregnancy. Its preoperative diagnosis remains a challenge since it presents quite similarly to tubal pregnancy and complicated ovarian cysts. Although in most cases, histology is necessary to confirm the diagnosis, we present an ovarian pregnancy in a teenager, correctly diagnosed during ultrasound examination.

Objective: To evaluate differences in the follow-up of recurrent unintended pregnancy (UP) between a former and a posterior episode. Methods: Retrospective study of women with recurrent UP comparing contraception and methods of abortion between the first and second episode. Results: Ninety-one women fulfilled the study criteria. The prevalence of UP was 13.7%. The mean time between abortions was 21 months (2-57). Before the first episode, most women were not using any contraceptive method (39.3%), while before the second episode most were using oral contraception (OC) (48.8%).
