Is it possible to change the time I take Vines to a later date?

Good morning, I've been taking the tablets at 20, I'm starting a new pack on Sunday and I don't know if I'm going to make it to 20 with the tablet, can I move that time? I'm going to the sea and in such heat I prefer not to take tablets with me. At this point, he is taking placebo tablets. Will something happen when, for example, I take a new tablet from a new blister at 23? And what if I wanted to change this hour (23) to 20, for example? On Sunday let's take a tablet at 23 and on Monday I can take at 20 and permanently leave it? Vines
