hysteroscopy

Michelle • 34, DH 37. ttc #1 for 4+ years
My RE wants to do a hysteroscopy before my transfer next month and the nurse said I have to have a pre-op for it, which I found strange - Is anesthesia used? I've heard some people were awake and others who were not. What should I expect in terms of recovery? I'm just trying to figure out if I'll need to take time off work... thanks ladies!
