Help needed about my cycle

Hi ladies, I'm a little confused and would like to know if anyone can help. When I was on the pill I would take a strip for 21 days and then have 7 days off. Now I would have my withdrawal bleed always 3 days after finishing the strip (which makes it 24 days out of the 28) now I am off the pill and counting the days since the start of my cycle, should I expect AF on the 24th day? - I hope this makes sense 🙈
