UTI while on RA Injections?

Hello fellow bad immune system havers! I wanted to see if anyone else has had experience with a UTI while on immunosuppressant injections for their own rheumatoid arthritis.

I discovered I had a UTI last Wednesday and quickly arranged a telehealth consultation, receiving antibiotics later that evening. Typically, I administer my Actemra injection on Wednesdays, so I decided to skip it to help my body fight the infection. I completed the course of antibiotics without any issues, and it initially seemed like the infection had resolved. I resumed my usual routine and took my Actemra injection this Wednesday as scheduled. (Note: I've only been on weekly Actemra shots for 3 months- Previously was on monthly Simponi for a year with no relief. I've also ruled out pregnancy with a test.)

However, I'd started to feel as though the UTI may have returned, and a home test I took was VERY positive. My symptoms have increased a lot, accompanied by pain in my guts and lower back. My partner is concerned that the infection might be spreading. We suspect that the UTI may not have fully cleared up and could have flared again after my Actemra shot. I'm closely monitoring my symptoms, and fortunately, I still have a week's supply of antibiotics left.

I would greatly appreciate hearing from anyone who has gone through a similar situation. Does anyone relate? Did the infection fully resolve for you? Were there any instances where a hospital visit became necessary? I’m feeling quite anxious about this. Cheers ;_;
