1)The ipill is not considered harmful to your health or body. Keep on using it when the condom fails.
2) it depends on if he had semen, and where exactly he touched you. Your vagina is the hole going inside your body. Everything else is called the vulva (lips, clitoris, pee hole and the area between your lips). So if his penis touched your vulva, the chances are very small. You must however be very careful when he touch your vaginal opening or insert his penis into your vagina.
It is best for him not to put his penis between your lips without a condom. Outside is not a big issue.
