Here's the thing...there are several possible outcomes from feeding a meal that is too large to any snake. Everything will probably be ok judging from what you said but it doesn't change what could happen.
1. The snake digests it and everything is fine.
2. It regurgitates it and resumes feeding after a few weeks without eating...everything returns to normal.
3. It regurgitates and dies.
4. It regurgitates it and is never able to keep food down again until it dies.
The deed is done so that leaves what do you do now? Leave the snake alone. If your husbandry is correct there is nothing your interference can do but make the situation worse.
