Uti recurring

I’ve never had one before since I had my baby I had two of them. My most recent one happened less than a week ago and as of yesterday I finished the antibiotics. Today, I woke up with a ton of pressure like I did antibiotic. Is there something I’m doing wrong? I have to follow up with the dr in a month since blood was found in the urine. Which is common for uti, it’s also common in bladder cancer (yes I google).

I’m on my period so can’t really be rested for much.
