Complications

Faith
I'm 32w4d pregnant, I've had almost constant urinary tract infections since I was 14 weeks, I've been on a daily antibiotic since week 16, and at 32w exactly I was hospitalized for a severe kidney infection, for 2 days. Last night I woke up at 5am, peeing fire every five minutes and it hasn't stopped since, I have a doctors appointment at 1:20 today, but I can't understand why they won't do something. They just throw me on an antibiotic that doesn't work, then even hospitalized, they didn't do anything, except for fluids and an antibiotic, that is now out of my system, so the infection is back. What should I do?
