future child

My friend khalil and i have had sexual contact but he has not exactly inserted himself all the way into me. I've been feeling sick like i'm going to throw up lately. i have had these symptoms before my cycle but i am not sure if i am pregnant. I have been going to the bathroom more often but that was going on before we he had sexual contact with each other. I don't' know if my body is just trying to let me know that my cycle is coming soon but i really need to know. A psychic from another website told me she didn't see my pregnant from her end and that she didn't see it from him. Then she said i should get a cheap pregnancy test to make sure so it doesn't really make any sense to me if its not by him i don't need to get a pregnancy test because he's the only one. my question is am i pregnant?
