Should I get a second opinion?

I've been havin abnormal papa since spring time. I've gone every three months for repeats they have still been abnormal. I go in October and it has gotten worse so I go back for colposcopy in November. While at my colpo appointment I'm told I am veeerrry close to the cancer point and he begins to tell me about a procedure I will get when I get my results. I get my results and my dr says no procedure I'm back to where I was before, just abnormal. Mind you, this is just two weeks after a colpo and about four after the bad pap. My question is has this happened to anyone else? I feel like it's too short of a time span to go from abnormal to terrible back to abnormal. I do trust my dr but I'm also thinking he's human, he's going to make mistakes. I'm wondering if I should go see someone else and maybe get a second opinion. Also I'm due back in February for another repeat pap.
