Sick or prego?

I know the only real way to know is to take a test but id also like to hear other peoples experiences and opinions. Right now i am 11dpo, i have 4 days until AF. I had a pap on 6dpo. Since 7dpo iv had a lot of headaches, iv been really nauseous on and off, iv been peeing like crazy, iv thrown up in my mouth a few times, iv been really tired, gassy, stuffy nose and all of this has been with no fever. I thought i was sick but now im starting to think im pregnant. I mean if i am im kind of shocked because i didnt think you could have these symptoms this early.
