not having a good time

I've had a migraine since last night before I went to bed and it took me a minute but i got a few hours of sleep (not that they were any good). Woke up about half an hour ago, still with a migraine so I took some meds for that but this time i was feeling a bit nauseous as well and when I tried to go back to sleep nothing was comfortable and I started getting hotter and more uncomfortable so I went to the bathroom because I just had this gut feeling, pun intended, and I threw up about four times. My brother came in there to make sure I was okay but then he said (jokingly) "you're pregnant" but then I got thinkin. My boyfriend and I last had sex a little over a week ago, no protection but I am on the bcp. Do these sound more like period symptoms or early signs of pregnancy?
