UTI ?

So I lost my virginity around may last year ever since I’ve had a foul urine smell like eggs . I went to urgent care and they took a urine culture and tested for std and sti & BV it was all negative except for uti. They gave me time release pills but I can’t take pills so I opened them up and poured them in water and apple sauce and they didn’t work and the smell is still there … does anyone know what if could be ?? Also sex doesn’t feel good to me … there’s also once in a while pain down there

The foul urine came after the day after I lost my virginity and Idk if I nvr like sex bc ever since the first time I had the foul urine smell
