Skipping Placebo Week

So Ive been skipping my placebo week for about 4 months. The last two ive had spotting around the same time. Next month I have a beach trip with my boyfriend and I dont want to surprise spot again. Only, im afraid if I take a placebo week I'll ruin my body's process of getting used to that. Should I take a placebo week and just reset or keep going and risk spotting?
