Spotting

I've been taking Tri-Lo-Sprintec for about a year now. I've never missed a day, but my boyfriend and I are in the process of moving so I've been stressed and have been taking my pills at different times of the day (9am, noon, 6pm, 11am, etc). It's a week before my placebo pills and I noticed some brown spotting and acne break outs. Of course it's given me pregnancy panic, as usual, but my boyfriend and I have never had sex without a condom, so that's unlikely.

Should I contact my doctor?
