UTI peeing blood

I just developed a uti today. This afternoon I had a slight burning when I peed but didn’t think much of it. Sometimes that happens and I drink a lot of water and it goes away. Instead it got progressively worse and I can’t get off the toilet because the urge to pee and now I’m peeing blood.

I had my husband pick up AZO urinary pain relief max strength which I took over an hour ago and hasn’t helped.

Any tips on how to relieve the pain until I can cal the dr in the morning? This is almost unbearable.
