Job pay? Kind of confusing

Okay so I started working at chucke cheese and the way they work they pay every 2 weeks. Well I asked my coworker when was their last pay day and it was Jun 29th (wed) *btw we get paid every other wed* anywho well I started working last week on July 8 & 9 and this week I work July 14 & 16 & 17. I calculated it and supposedly my coworkers get their next check this wed coming up which is July 13 well since I haven't worked 2 weeks I figured I get my check on the July 27th since that is the next pay day after July 13th. So that's 3 weeks of me working and it makes sense since I worked a week after their last pay day. Am I wrong or do I have it right? Please let me know since my job doesn't really tell me when the check is there. ( I put a calendar so it's a little bit easier)
