Another period?

I have a pretty regular period every 4 weeks. I got my period two weeks late (Dec 30-Jan 4) but now I am freaking out. I had some spotting on the 9th of Jan then on the 10th I had a bunch of white discharge. Today(11th) I had white discharge again this morning. This evening I felt moisture so I went to the restroom and it was white discharge and bleeding as well. What could be going on?
