The problem is vaginal discharge
and the fear is abnormal PAP Smear
The color of the discharge being orange or reddish yellow, was it soon after the intercourse ? in which case YES u do need to get further on colposcopy
Sometimes it just could be a chronic infection of the mouth of the uterus ( Cervix). which could give an abnormal PAP smear, however, do wait for the Colposcopy biopsy results, which would be very helpful.
Medicine causing such a color of the discharge is unlikely unless there was some injury at the time of insertion of the medicine. the discharge of medication is usually mucus like.
Consider taking anti-cervical cancer vaccine
to protect your self, ( anti-HPPV vaccine) if it is negative fro cancer.
