But does it sound like genital herpes to you?
did you have any actual std testing done? If not, you really need to be seen and get it done promptly. Trichomoniasis and other std's cause the discharge you had and can affect your future fertility so getting properly diagnosed and treated now is in your best interest!
since it's been almost 3 months, you can do your full std testing now - trich, gonorrhea, chlamydia, syphilis, herpes , hiv and hepatitis.
