pill, if used correctly, is 99.9% effective. if you don't have sex with her, that is 100.0% effective. your adding a condom to the mix will not increase it to 100%, but likely will nudge the odds a bit more in your favor.
Please note the phrase "if used correctly". that means taking it at the same time every day, not skipping days, checking for interactions with other drugs. Antibiotics GREATLY decrease the effectiveness of most birthcontrol pills so if she's sick, or taking meds, use a condom or abstain. So, yes, cumming inside her increases yoru chances, but, really, sticking your wang in there at ALL gives those same chances.
