Help me please :( pee problems

Hey everyone! So since i became pregnant I’ve had this issue where it feels like i have to pee SO bad and barely anything comes out. It’s gotten so bad recently that it feels like all i do is think about my bladder. I can barely sleep at night because i can’t fall asleep due to feeling like I’m peeing myself (it’s like an urgent feeling like you’ve been holding your bladder for hours and hours) and it HURTS! I’ve had several uti tests and cultures to make sure i don’t have infections and they all come back normal. My obgyn doesn’t seem to care since the uti tests are normal and just tells me to deal with it and that it’s “normal” but none of this seems normal... i don’t know what to do anymore!
