UTI :(

Help me please!!

So I'm pretty sure I have a UTI it stings when I pee and I constantly have to pee but it's not a lot. And I'm taking azo urinary pain relief but it's not working for me. And it's the weekend no health clinics open on Sunday. Please give me advice on what to do

Update: Thank you guys for your advice I finally went to the doctor yesterday and got the antibiotics
