Advice on hysteroscopy

So had sonohysterogram today and they found a polyp that will need to be removed Friday. I'll be put to sleep for it. Also my cervix is really narrow so they're going to have to dilate it so the transfer goes smoothly. Any advice from someone who has had a hysteroscopy? Painful afterwards?? I have to insert cytotec vaginally which causes severe cramping and bleeding so I'm nervous!
