An origion scan is when the package arives at the hub is unloaded off the package car and is sorted to its outbound trailer, it is scanned after unload and shows an origin scan. Pick-up pieces should not be scanned at pickup unless it is an ASD that someone hand you not at a scheduled pick-up. If origin scan were a pick-up scan less than 1% of packages would have one.
Your package is an a trailer headed to its destination hub, when it gets there it will show an arival scan as it hits the lot, next and sometimes the next day, depending on the arival time of the trailer, will be out for delivery, meaning it was scanned on the morning preload and loaded into a package car.
Once you see that scan then it will be delivered that day.
Time in transit does not count the weekends, however UPS will use the weekends to move packages like your so they do not have to use airplanes.
Hope that clears up your concerns.
