Hello, I hope this helps. I have had two of these. Would describe them as odd and a little uncomfortable but not painful. Shall you be having any drugs to help? The second one I had was done by a "learner!" and took longer and with no drugs. A very experienced and kind nurse held my hand.
Good luck and you can pm me if you want to chat.
