You've learned the first lesson Sophia. Feed your snake yourself. When it comes to live feeds you're the one who needs to be there. I'm not being harsh, just realistic that no one is going to care about your snake as much as you will.

I'd just very gently check her over as much as you can without moving her about a lot. Nudge her over and check the substrate directly under her for any sign of continued bleeding after the feed. It's likely it was the rat and she just squeezed it enough to pop a few blood vessels in it as she moved it around to eat it but it's best to have a good look at her just to be sure she's okay.
