Changing the time I take my pill

Hey guys!

I have to change the time I take my pill as Im starting school next week. Ive taken it for about 4 months now and always took it at 10AM. Ive already started yesterday (monday, 26th) taking it at 5PM. Im on the desogestrel minipill.

I just came here to ask for confirmation, as google hasnt helped me much. but I have to wait a week before engaging in condomless sex again, yes? I waited a week when I first started so Im assuming its the same this time.

If you take the time to answer, thank you!
