I know you don't want to, but give her a few days to settle in.

I woulld just offer her a meal on your next feeding day. In true blood form I'm sure she will eat.

With my big red I wait 2 days after feeding to handle and have had no issues.

Bloods drink alot of water. If you handle them soon after they drink some of the water will come back up. Don't freak out if this happens. It will look and feel just like water, cause it is.

As for the amount of time. 5 minutes should be fine to start out. Read the snake. If it seems content being handled then start extending the time.
