Am I supposed to bleed?

I recently went on the pill and yesterday I started spotting Iv got one more day left on this strip of pills.. Is it normal to bleed before I finish the strip? (Just to add I had a baby 10 weeks ago, not to sure if my body is still getting used to not being pregnant) help 🙈😁
