Pregnant.. Option of dad?

So I normally don't sleep around.. And of course when I did this time it bites me in the ass and now I'm pregnant. I had sex with a guy I was talking to unprotected and then 5 days later another guy I was talking to but with a condom.. I need a paternity test done anyway just don't know what to do if the guy I slept with unprotected isn't the father his family already knows.
