Placebo pills early 🤔

I’m trying to switch the weekend of my period. In an LDR and reallllyyy wanna spend that sexy time with him haha. Is it possible to take my placebo pills this week and just flip flop the hormone/placebo? As in, instead of starting my placebo pills this Sunday, I take them now and then continue with the medicated pills? (If that makes sense) Will this make my period last longer?
