Temporary uti relief

I'm currently 19 weeks pregnant and I'm experiencing what I'm guessing symptoms of a UTI. Always feel the need to urinate, discomfort while peeing and just overall pain and discomfort in the groin area, accompanied by minor back pain.

Anyways, I cant get in to see my doctor or OB until Monday and I'm wondering what I can do temporarily if anything to relieve some of the pain and discomfort until I can get some antibiotics from my doctor on Monday.
