Missed a pill

Hey! So I had a bit of a stomach bug and I took my pill at my normal time , made it 2 hours then threw up. I didn't take another pill out of fear I'd throw that one up too and throw my cycle wayyyy off.  I was just wondering if I was still protected against pregnancy? 
And I am on a combination pill and I am usually always on time or within a 1 hour window of my normal time.
