Pill - how strict do I need to be?

I’m on the combined pill, and I’m really paranoid at taking it at the same time every day.. I’ve set a reminder on my phone so I remember to take it, so I probably take it in a 5-10 minute window each day.

But I keep seeing comments about how the combined pill you don’t need to take as strictly each day? Like in a 12 hour window... Is that true?

I mean the alarm on my phone helps me take it, so I’ll probably keep that, but can I relax a little?
