Timing for the Pill

I am new to the pill.. I'm on sprintec which is a combination of progesterone and estrogen. I set an alarm for 8:30, but usually I just have it every day after dinner which has been around 7:30. If you don't take it at the same exact time, do you fall under the "typical user" statistics which is like 94% effective? I can not risk pregnancy right now, so I was wondering.
