I just had a colposcopy today, and wanted to chime in in case others lookd this thread up.
I did not experience any more pain or discomfort than a regular Pap test. It took about five minutes, no kidding.
I listened to loud music through headphones. i found the distraction extremely helpful. I also instructed the doctor to NOT tell me, just do it. I find the anticipation and anxiety is worse than the actual procedure...any procedure, really.
I have no bleeding and moderate cramping. I forgot to take some ibuprofen beforehand, but I did when I got home and I am quite functional.
On the good side of it, she said (yeah, get a 'she' too-another anti-anxiety method) that everything looked perfectly healthy and thought the irregular Pap might have been a false positive or whatever it was cleared up on it's own. So Hooray! If anyone has questions about the procedure they can pm me or ask here.
