A colposcopy is done to further evaluate an abnormal pap smear. Your practitioner gently places an appropriate size speculum into your vagina and identifies your cervix. A cotton swab is then used to apply vinegar to your cervix. The vinegar will cause abnormal cells on the cervix to "light up" . When biopsy specimens are taken, it can feel like a menstrual cramp. A liquid iron solution is placed over the biopsy area to stop any bleeding. Usually, the cramping resolves in a few minutes.
This solution causes a discharge that looks like coffee grounds for several days. You should not put anything into your vagina for at least one week after your procedure.
