Not all your posts are converted into activity. A maximum of 14 posts would be added to your activity every 2 weeks. The other posts that weren't added to your activity would be added onto other fortnights.
If however you haven't reached your 14 activity limit in a fortnight, new posts would update your activity within an hour.
