I Had Pap Smear Over A Year Ago. Test Showed

I had pap smear over a year ago. Test showed high on high level and low level of dysplasia cells if that makes since, I have the correct terms, just not in front of me. This was the second time, the first time about two years ago the leep procedure was performed. The Pap smear from over a year ago, When the levels were high a Colops- was scheduled, (with the microscope) they were unable to perform because they said my cervix is closed, I was to come back for another pap in 6 months. I thought they should of done something then. Dec.14,2015, had another pap smear, Dr. said my cervix is closed.. why is my cervix closed and what should I expect them to do... I am concerned and it could be cancer now... Thank You.
