My only "complication" related to the surgery was a Candida yeast infection at about 11 days post op which made dilation miserable by making the dilator feel like it was coated with sandpaper. It took 48 hours to clear it up with oral and vaginal medication. In checking around, that one is about 1 out of 15 patients that will get it. As I said, it made life miserable but survivable until the meds had kicked in. For several weeks, the dilation can seem like a major complication all by its lonesome, but be gentle and persistent and you will be fine.
Have a good Ob/Gyn picked out close to home, and briefed on the chance of needing their help. Be sure to give your surgeon permission to share the records with your normal health care team, and to be able to have phone consultations with all doctors involved.
I am not nearly as athletic as Jenna says she is, but I concur that the fatigue is a real problem the first 6 or so weeks, and its made worse that you cannot sit for long periods of time to rest.
I do know of people that have gotten much more serious problems which the doctors warn you about, but for everyone with one of those, I know of three people who asked for trouble by not following their post care recommendations. Some of those stories are so stupid that you are almost glad the complication happened to 'em. (Note I said ALMOST.)
