hi there is the rhythm method like this a method of avoiding conception favoured by the roman catholic church by which sexual intercourse is restricted to the times of a woman's menstrual cycle when ovulation is least likely to occur. just google rhythm method for far more info but if you really don't want to get pregnant then there is the bc pill unless your against them or your body cant handle them but have you thought of the mini pill its just one hormone and low dose. then you will know for sure. remember safe sex is the best sex. good luck
