Pregnancy without penetration ??

Hey, look I don't want to get any hate for this but I've done some research and I got myself worried. My boyfriend and I (17) showered together like two days ago. We did not have sex, no penetration, but fingering and oral. I've had stomach aches and cramps today and I think I'm really stressed out, he says there's no chance pregnancy can occur but I've read other things ?
