Mycoplasma hominis came back??

In April I tested positive for ureaplasma and mycoplasma hominis. Treated with doxy and felt better. Eventually I felt symptoms again and had BV and kleb p UTI. 5/29 I was negative for hominis and ureaplasma. Didn't even think of testing cuz I stopped having sex so I didn't think I could get it again.

Now it's September lol. I've had UTI symptoms on and off. I got diagnosed with interstitial cystitis which I'm getting bladder instillations for. I had c. diff from antibiotics for 2 months. I'm still recovering from that. I had the kleb p uti for like a month and I never used antibiotics for it because of the c diff. I road it out and tried pomegranate husk, biofilm busters, and oil of oregano. It seemed to work, eventually my urine cultures we're coming back clear or with urogenital contamination.

Anyway, I just tested for myco/urea again at a new urogynecologist. And I came back positive for mycoplasma hominis. How could I have this again? Does mycoplasma form biofilms?? I haven't done anything sexual for months. And now I'm gonna have to use antibiotics again and risk relapsing with c diff. Could antibiotic use or other infections trigger the mycoplasma coming back somehow???

I'm in hell lol. And sometimes I think I don't have IC and this is a UTI the whole time. Even though it seems certain foods and drinks trigger bladder pain. My bladder lining is definitely damaged.
