Xulane Patch question

So I've been using Xulane patches for almost a year and have had no issues. I use them properly per the included instructions. In the past I've put on a new patch on my period week so that I can skip it due to vacation and such and have never had any issues. I did that again this week, but it's like my period is still starting. It's light and barely there, but still having cramps and all.

As much as I want a baby, my fiance and I are not financially stable enough so I just want to ensure my birth control is working how it should.

Has this happened to anyone else before?
