Paranoid

Ok ladies so my boyfriend and I were rubbing it up...naked of course...and I'm not on the pill and he didn't have a condom on because we never had sex and didn't plan to. There was no penetration and he never came. My mom and sister say I'm paranoid since I'm only a day late getting my period and they say that I'm stressing myself out which is making it late. Are hey right? I'm not pregnant?
