pregnant?!

I may be pregnant, I'm not sure. Me and my boyfriend are long distance currently due to college (but I'll be going back to my hometown for a new college I plan on going to) I just visit him two weeks ago. So I removed my birth control because 1) it was making feel sick, and 2) I'm not always seeing him so there's no point in using it if I'm not having sex all the time since he's not here nor am I there. We got carried away and had sex multiple times without condoms. Is it possible to feel pregnancy symptoms early on? If I'm pregnant I honestly don't know what I would do. My mind is torn between an abortion or going through with my pregnancy.
