Just keep an eye on her, give her extra days before you mess with her and see how it goes.

Back when we had only a couple of snakes and bought our live prey from a pet store I used to use my own hand to measure with, as in, I need a prey as big around as this or that using my own hand as the measuring instrument. It really helps since pet stores don't put a warning on their rodent enclosures..."rats may be bigger than they appear".
