Afraid Im pregnant

I'm really afraid that Im pregnant. I'm 19 and in college and I am really afraid. I've been peeing a little more than normal and I have a yeast infection. I'm not due to get my
Period for another week or so but still Im scared. I'm like freaking out and Im not sure if I could go through with an abortion. But I don't think I'm capable right now to have a baby. I'm not in a relationship, my parents would cut me off. Id be alone and unable to support myself. And I'm in school. And please don't hit me with then I shouldn't be having sex. I know I messed up.
