How will I know I’m late?

If I just ovulated on 8/24 will my period come in 2 weeks? My apps all say it’s due 8/28 but I for sure ovulated on 8/24 (I used digital opk& had all the symptoms) I’m just curious because I’ve never ovulated this late before.... I am also hoping we timed our sexy times enough to have the sperm there ready and waiting for the egg. 🙏🏼🙏🏼

We BD on 8/17,8/21,8/23,8/24. All within my fertile window. I’m hoping this is our time but I want to know when to expect a period so I know when I would be late or when I should take a test!
