UTI?! HELP!

I'm 23 weeks now and I've had slight UTI symptoms since early Friday. I've been chugging water, taking cran pills and peeing it all out while resting. I still only have minor symptoms and I'm not in a lot of pain, but today I've had a little more pressure on my bladder. 
My question is... Should I make a trip down to urgent care or wait to talk with my OB tomorrow morning when they open to see what they advise? Any advice, experience or help is appreciated!
