Had one 4 years ago. Stayed in overnight. Thought I'd be back to work in 24 hours but took 2 weeks! I didn't feel great for a day or two, but after that it was fine. Not particularly painful, just rather uncomfortable, but it took me a while to get back to work just because my stomach was very swollen and tender and I couldn't face being bumped around on the underground. She will be fine, honestly. She'll just need TLC and a bit of company for a few days. Good luck!
