I'm a 15 year old female. For the past 3 or 4 days, I've been sick, and I keep feeling like I have to vomit, especially after I eat. For the first few days I've had a fever, but now the fever is gone and I still feel like I have to vomit. I do have a boyfriend but we haven't had sex, and I haven't had sex in over a year so I don't think I'm pregnant...help :[[
