I'm 16 & I feel like if I'm pregnant!

Okay.. This one night a friend of mine came to pick me up. To make the story short we ended up at his house. He started to lay me down & all. I didn't want to have any sex! he didn't push me to have sex. So I let him finger me? It hurted. But I don't remember if he was jacking and I don't know if he had any sperm on his fingers? But than he fingerd me again. I didn't really want him to do that to me, I felt disgusted when he was doing it. ANYWAYS the next day my vagina hurted, and the whole day I felt sick to my stomach. I tried burping a couple of times but it really didn't help. Until later on that same day like I woke up in the middle of the night throwing up. But it was all the food I had ate! the next day I felt the same but I didn't throw up. And when I went to use the restroom I saw this like kind white slimy stuff come out of my vagina? But it was only that one time. Than for 2 days I couldn't eat, the food just smelled & looked disgusting.. Or after I had ate. Now i can eat. I thought maybe it was because I felt so disgusted of what I did to him (HJ) & what he did to me. But than the next day my boobs felt sore, now they are not sore anymore. But my stomach oddly feels like A not.. I'm so scared! I don't want to be pregnant. & I never even wanted him to do the things he did. I just need a answer that can help me a lot. But the sickness went away.. THANK GOD! I can eat now. And my boobs feel totally fine now! SO please help me out with an answer back please! thanks.
