Ugh. UTI at 32 weeks

I'm in so much pain!! The er Doctor said the UA was not "flouridly infected" but I was having a ton of bladder spasms as well as back pain (I have a long history of kidney stones and have had hydronephrosis on both sides since about 17 weeks. Spent the whole day there for them to hem and haw to finally decide to treat the bacteria since it seems like that's all they could do! Hoping I start to feel better by tomorrow. This stinks!!
