LGSIL of the cervix is caused by many factors including early initiation of sex, HPV (strains 16 and 18) and Herpes infection, and other sexually transmitted bacterial infections. Pap smear can show false positive results for LGSIL. Many a time, these lesions regress by themselves after treatment of bacterial vaginal infections. However, you may proceed with your gynecologist's advice of colposcopy and biopsy and if nothing worse is detected, you may follow up with Pap smears.
Since you have been vaccinated with Guardacil, this may protect you from strains of HPV virus with which you have not already been exposed.
Genital warts are caused by HPV virus strains 6 and 11 and are relatively innocuous causing condyloma on the cervix, vagina and vulva. We don't know whether these strains of the virus have already infected you and your partner before you received the Guardacil in which case you may still get the warts. Using barrier contraception(condoms) would still be a good idea, in spite of using injection provera since it would protect you from various STDs.
