preterm labor.

Samantha
So last night I ended up going to the hospital for all the cramping a, contractions, back pains and turns out I was having real contractions and they ended up giving me a shot for them to calm down, they ended up sending me home after that and said to come back if it keeps occurring or I have worse issues. 
Well they're back, I'm thinking about going back. But I was just curious as to if anyone else has these issues. I have a UTI that won't go away so I'm wondering if it's from that or not. 
I'm almost 33 weeks.
