Help pls

Hi guys! I really need to ask you something..

I'm still a virgin, and I was just like.. you know.. playing around with my boyfriend and he kinda tried to get it in you know, but I said no so we stopped. Since that, I feel kinda funny.. like my boobs hurt and i feel a little bit sick, I don't feel like eating... Is it possible to get pregnant from that kind of stuff? Or maybe you can tell me what is wrong, I don't know..
