Timing?

For the past week or so I've been taking my birth control at a random time within 7-8am. I usually only take it at 8am but I've been waking up earlier lately. There was one time where I took my pill at 6am, on July 1st, because I was worried I'd forget if I took it later. (I couldn't go back to sleep).

Am I still protected from pregnancy effectively or does this raise the risk too much? (my partner and I gave had sex twice within the past week, but both times he used the withdrawal method.)

I know I'm supposed to take birth control at the same time every day, but I don't know if taking it at a random time (between 7-8am) lowers the effectiveness of them a lot or not.
