Super confused

Okay so I got ovulation test strips to start using next month since I already "ovulated" this past week. But for fun and out of curiousity I took one today and my period is suppose to start in 11 days and my cycle is 29 days long. Does this mean I'm ovulating later than I thought I'm super curious how this all works. Here the test I just took so any advice would be great.
