I was on Triphasil 21 for something like 15 years and I always took it in the morning when I got up. Sometimes I would sleep in, etc. and never had a problem. I know I've even forgotten to take one and taken two the next day and everything worked fine.

I don't think that taking it a few hours late every once in a while will make any difference, but everyone's bodies are different and the various brands of pills may make a difference too.

Good luck. What does your doctor say?
