Should I check?

So me and my boyfriend had sex for the first time this weekend, it was amazing but he's nervous I might be pregnant. He didn't cum or anything because we stopped before that time, should I still check? I mean I don't think I am but I want to be sure, if I should, should I go down by myself or tell my step mom and tell her what happened? What's the best??
