Am I pregnant if he never cam?

Ok so me and my fianc� have done stuff for a few months now but it's never been actual sex, pretty much just him in me and me grinding for a few, he has never cam or anything but I have heard bout pre *** and lately I have been tired, feeling sick, and belly aches... Somethings I get gasy for no reason... I don't wanna get a pregnancy test till I see if I miss my period but my step mom, and dad keep saying I'm pregnant but they don't know we have done anything, I'm very worried and just wanna know if he only pre cam in me I can be pregnant?
