do I have a uti?

Danielle • Married my best friend on 4/11/2015. I have a son—rainbow baby born 2016, and trying to grow our little family💗💗💗
Experiencing some symptoms! I'm drinking tons of water but barely yielding any pee. Yet I feel like I have to pee a lot and very often. It has a different kind of odor to it than usual. I'm having contractions and back cramping. Along w lotsssss of sharp shooting pain in my vag area. I'm looking for advice here until I can see my dr tomorrow as the office is closed. 35 weeks along now
