UTI advice or remedies?

Av

If you have any tips I’d love to hear.

I got married Saturday, after a year of waiting, I had sex with my new husband on my honeymoon. After 2 days I got a UTI and it wasn’t that bad. It’s gotten worse as the week goes on. It’s painful to have sex, to pee and just in general. Today

I started peeing blood. I’ve been drinking cranberry juice since day one. My sister gave me some prescription nitrofurantoin, a antibiotic but I don’t see a change.
