    Results


    A total of 2858 women enrolled and 1680 completed the study. Forty-six pregnancies in 2401 women aged 18–35 years occurred after COC initiation and up to 7 days after last DSG/EE or EE-only tablet was taken. When cycles in which another contraceptive method was used were excluded, the PI was 2.68 [95% confidence interval (CI), 1.96–3.57]. The cumulative pregnancy rate after 1 year of treatment was 2.47% (95% CI, 1.85–3.29) for all users aged 18–35 years. When only cycles during which women considered compliant were included, the PI was 2.00 (95% CI, 1.39–2.80). AEs were similar to those seen with other oral contraceptives.

    10. Perfect use of oral contraceptive pills, Depo-Provera, and Implanon, and typical use of Implanon


    Although the lowest reported pregnancy rate for the combined pill during typical use is 0% [24–25], recent studies indicate that pregnancies do occur, albeit rarely, during perfect use [26,27]. Hence, we set the perfect-use estimate for the pill at the very low level of 0.3%. The lowest reported pregnancy rate for the progestin-only pill exceeds 1% [28,29]. It is likely that the progestin-only pill is less effective than the combined pill during typical use, since the progestin-only pill is probably less forgiving of nonadherence to the dosing schedule. Whether the progestin-only pill is also less effective during perfect use is unknown. [...]

    Es ist schon möglich trotz Pille und Kondom schwanger zu werden.


    Pille wird nicht regelmäßig zur gleichen Uhrzeit genommen, Kondom ist gerissen, Aufnahmestörung der Pille wegen Durchfall oder sonst irgendwas.


    Ich habe eine Freundin, deren Sohn ist so entstanden. Antibiotika, leichter Durchfall und Kondom gerissen.


    Jedoch frage ich mich auch, was das für Symptome sind, an denen dein Freund das erkennen will...


    Bist du gereizt? Wäre ich auch, wenn ich Angst hätte, was du anscheinend hast vor einer Schwangerschaft.


    Ist dir oft schlecht? kann auch psychisch sein...


    Die Psyche macht verrückte Dinge...


    Warum kannst du nicht allein raus? Oder hast du nicht eine Freundin, die dir einen besorgen kann und vorbei bringen beim Lernen zusammen oder sonst iwas...?
