I'd say your contraception methods are risky. I don't have personal experience with encare ovals, but I'm pretty sure it is supposed to be used in conjunction with a condom. Also, the pull out method is far from fool proof. Sperm can and does leave a mans penis before he ejaculates in his pre-ejaculate. If you absolutely positively do not want to get pregnant, then I'd either use condom and spermicide every time, or you or your partner should have sterilization surgery. Even those methods aren't 100%. Close to it, but not 100%.
