No PMS?

Dee
I got my period in October as usual, then got it again October 31st-November 4th. Now I'm supposed to start it according to my personal tracking tomorrow or by Monday. I have no PMS symptoms and I usually get them a week before I start. My boyfriend and I didn't use protection last week but he pulled out. Could I be pregnant? Or is it normal to start my period early then get it late? Or maybe just get it early again in December? What's normal? 😫 Any opinions or advice?
