You : You may have suffered some vaginal trauma during intercourse, have an infection, or have a urinary tract infection(uti). The fact that you missed your period is likely not related, however you will need a pregnancy test. Schedule a visit with your family doctor or gynecologist for evaluation and work up of your vaginal complaints. All the best.
