Spotting while on the pill

Hi! So I started taking the pill as a form of birth control earlier this month and once I finished my first 21 pills I threw out the other 7 and immediately started on a new pack. Now I am currently experiencing spotting while still taking the pills with hormones even though my intentions were to skip this period so I didn’t have to worry about that. I am supposed to be on my period right now at this moment so I was thinking maybe that’s why I am experiencing spotting but I’m not sure.
