What Treatment Is Suggested For Mononucleosis And Greenish Watery Discharge?

I am in the 6th week after being tested positive for Mononucleosis. Along with this disease, I had huge vaginal ulcers that were very painful and caused a greyish discharge. All tests of the vaginal ulcers were negative for STDs, bacterias and viruses. The sore are now healed but I still have a greenish watery discharge with no odor. The doctors say I am negative for yeast infections and not to bother with over-the-counter yeast remedies because it is a symptom of the mono. How long will this discharge last?
