Colposcopy for abnormal pap smears. This is a procedure in which a lighted, magnifying instrument called a colposcope is used to examine the cervix, vagina, and vulva. During colposcopy, an instrument called a speculum is inserted into the vagina to widen it so that the cervix can be seen more easily. This feels like a prolonged pap smear, a biopsy may be required. The biopsy is quick and feels like a cramp that, while uncomfortable, is very brief in duration. You can participate in your normal activities the day of the colposcopy. We usually recommend pelvic rest for 24 hours. – no sex or tampons or other objects to be placed in the vagina.
