Please help! Really confused!!

I’ve been on the combo pill for over a year, never miss one, and am always on time. I typically get my “period” on the fourth day of the placebo pill week. But this pill pack I ended up getting spotting a week before my placebo week began and than continued to spot until a day ago which I would have now been on the placebo week for 5 days. So in total I was spotting and one day of red blood for a total of a week and 5 days. I’m confused why this happened? I’ve had where I get my period a couple days early on bc but never a full week early. I took a pregnancy test the first day of my placebo pill week because I was concerned. Is this normal even after being on the pill for so long?? Here’s some pictures for reference of what the pad looked like during the time of spotting. So was this just an early period? Or do I need to be concerned about pregnancy??
