It is good that you are following up. That is the best thing you can do. Although I am not sure I could put myself through another colpo based on HPV alone. But my colpo experiences have been really bad
You are smart though, there is this lady on another forum that posts quite regularly who had regular paps for decades. Well, her dr decided to do an HPV test (for no apparent reason other than she had never had one before) and it came back positive for HPV but her pap was still normal. This lady (not the dr) pushed for a colpo just to make sure everything was ok and it came back that she actually already had cervical cancer in the canal, which only the ECC would have caught (not the pap). I am not saying this to worry you - in fact, that kind of cancer it pretty rare, but if it wasn't for her determination and a "gut feeling" (she said) then her situation would have been much much worse as the cancer would have advanced undetected. Anyway, so kudos to you for keeping on top of the situation!
