I nursed Max about 3 hrs after my d&c. I woke up from the anesthesia, went to recovery for an hour, went home and nursed. My l/c said that as soon as I was out of recovery, the meds were mostly gone from my bloodstream/milk, and it would be fine.
The other thing you can consider is her age. If she was an infant, you may feel differently. I think nursing that night should be fine.
