You might ask your doctor about doing a cold knife cone (CKC) biopsy instead of another LEEP. The LEEP singes/burns the edges of the tissue sample, but the CKCs edges are clean cut.
I don't know how old you are or if you wish to maintain fertility, but those are issue to discuss with your doctor.
Has he/she ever done an ECC (endocervical curettage)? It checks the cells in the cervical canal which are different types of cells than on the outer cervix.
Take care and write back!
