Implantation bleeding. ?

My period isn’t supposed to come till around december 8th. I’ve been having this light spotting. First Monday came along I had this spotting I thought AF was here but she wasn’t. Tuesday came I had no spotting. Wednesday came I got little spotting again. Thursday (today) I got little spotting. Its so weird because I NEVED get spotting like this before AF she usually comes and deep red blood comes out right away. My period isnt due for another week and a half almost 2 weeks. This is strange for me that’s why I’m asking this. This has never happened.
