I Had Unprotected, Drunk Sex. I Know It's Very Irresponsible

I had unprotected, drunk sex. I know it's very irresponsible of me. It happened around 1:30 am Saturday I woke up and took Plan B at 8:00 am....later in the day around 6:00, I got sick. I'm not sure if it was because I was hungover or because of the ECP. Extremely nervous that I threw up the pill, I went out Abe purchased it again and took it today (Sunday) around 12 pm. I'm in middle of my cycle so I could be ovulating. Is there a chance I could still get pregnant?
