Mouse was too big

I may have fed my corn snake too big of a mouse...
I picked up a mouse today and all they had were large adult mice. Once I got it home it looked pretty big so I weighed it and it's more like a jumbo mouse. Although I've been feeding her small adults I went ahead and offered it. She grabbed it but then let it go which is very unusual for her. I was concerned at this point that it was way too big for her and I probably should've taken it out but I left it in there and eventually she got it down. It left a huge lump...
As of now she's in her warm hide but I'm concerned about this meal size. Does anyone have experience with feeding too big a meal and if so how did they do (any regurgitation)?
*She's a little over a 1 1/2 years old
*She weighs 217 grams
Thanks so much!

Not much you can do now, but wait... Make sure the warm side of her enclosure is warm enough. She will likely stay there as it will assist in her digestion. If she can get through the next three days without regurgitating, she should be okay. Don’t handle her or do anything that could stress her out. Just an FYI, in the future, you’re better off feeding a smaller prey item or even two smaller prey items than something potentially too large. If she regurgitates, wait about two weeks before you feed again and make sure that the prey item is smaller than what she normally would eat. Good luck with!

I just conducted an experiment feeding large mice to 8 young corns. I was feeding fuzzies, but jumped up to weanling size for them. None of them regurged, even though the weanlings caused a large bump in the stomachs. I was going to return to feeding fuzzies but decided to try staying with weanlings. Just leave your corn alone as Dennis recommended, and she should be fine.

Thanks guys! So far so good, she's still tucked away in her warm hide.
