I had one about a year ago. Very undignified, of course, but no more painful than any internal examination, better than many smears which I've had. Set off a bit of mild cystitis but otherwise nothing more than very transient period-like sharp pain whilst they wiggled the camera tube thing around, a few seconds only. It's a very thin tube which they insert. Biopsy pliers again was just a mild quick pinch.
So I'd say nothing to bother about (except the worry itself!). In my case they found a polyp (not seen per se on scans) which they wanted to remove but couldn't do there and then, so I ended up having to have a hospital admission and anaesthetic (day surgery) - but fortunately after a lot of anxiety it was all non-suspicious.
Perhaps there might be a bit of period-like cramping or post-procedural bleeding (they pump you full of a watery gel so that's got to leak out a bit... ) and if they find a polyp or fibroid and remove it there and then it'd be a bit more sore and whatever afterwards - so I'd plan not to go doing 50 mile cycle rides in your best white shorts, and make sure that you can rest for a night and a day if you might need to. In your case I think you're expecting them to remove a polyp/fibroid anyway, so I'd prepare for some internal irritation, mild soreness, maybe a period-pain like situation? Usual over the counter painkillers....
I drove myself no problem, but if you have a spare driver then I'd advise to take one just as a back-up in case you don't feel great. (Plus it's good moral support

Good luck.
