33 weeks pregnant, uti?

Just woke up with the constant urge to pee.... its so unbearable honestly.. I tried taking a bath, drinking tons of water and cranberry juice. I can't fall back asleep because of it. I feel like when I'm on the toilet I have to push out my baby... so much pressure..every time I'm on the toilet a little bit of liquid will leak out..also having to poop and have light cramping. what's wrong ??
