I think those percentages are per year. So, out of 100 women, 6-12 will get pregnant within a year. That probably includes failure to actually take the pill, taking it with antibiotics, etc.
A girl I know got pregnant after taking the pill with antibiotics, or stopping it because of antibiotics and forgetting to mention that? Something like that.
