Just had mine done today. Well the 19th since its 1am here. I guess everyone is different. I've read some ladies say it was just uncomfortable or felt like period cramps or a pap. I swear I don't want to scare you because it was very reassuring but mine hurt. I was holding the nurses hand and crying lol. They asked if I needed a break but I just wanted it done with! The worst part for me was when she pushed the dye through. As soon as they took the things out I was fine. Slight cramping still but not painful at all, so it might just be in my head. I would say it took 5 minutes or so. Luckily I had very nice nurses that told me how great I did lol.
