I am 19 years, have only had 2 sexual partners my entire life, and my current partner has been with me for 2 1/2 years. I have been hospitalized twice already in the last 3 months for P.I.D, both times they were not std related. I have been tested for every stds 3 times in the last year or two because i get frequent vaginal infections ( right now i have a vaginal infection, P.I.D, and tonsilitis), since I have no stds, and my partner is clean, what can be causing this? I had a cyst in the past that lasted about a year, also had frequent urinary tract infections, but now they're gone. I also wonder if me being 5'4'' and 86 lbs have anything to do with it?
P.S. I've searched on the internet for causes unrelated to stds, and all that comes up are std causes. It's not fair to have this label when I have no stds.
