1 Sex partner STI?

Stephanie • 19 - Sexually Active - Australia
I'm having uti like symtoms and took the same antibiotics as I did when I last got tested for UTI but the symtoms didnt improve so I went to the doctor and he is testing me for Chlamydia and Gonorrhoea. I've only had 1 sexual partner that lost his virginity to me too. If it comes through as positive, does that mean hes been around with other women?
