Went off pill almost 3 months ago now spotting

Hi everyone. I am new here and have a question. I just went off birth control At the end of September. My first af was normal but this month I had some spotting before and ended on Monday 11/9. Yesterday 11/12 I had light spotting right before bed and a little this morning. My question is, is spotting like this normal after being off the pill? Does this mean chances of getting pregnant this month are low?
