Umm my period is pink?

So I just started my period. It was two days late. My normal period is very bright and medium flow the first two days and gets heavier and darker the third and fourth day, and light on the 5th, spotting after that. It's been kinda regular, give or take a couple days here and there, for about a year now. So why is my period pink now? I'm not pregnant. I'm not on birth control. I haven't changed any of my habits lately. I just don't get why it's changing up on me. It's pink, and mucus-y, what is going on?? I have my normal symptoms (cramps, acne, hangry, etc.)  but my flow and color are all off.. Help??
