Bladder infection :(

I am so bummed and frustrated. I have a UTI/bladder infection that is so uncomfortable. When my bladder is at its fullest, I can barely pee. It's making me crazy. On top of that, the bladder itself is inflamed and pushing into the vagina, making it poke out just a bit. It is such a weird sensation and I am terrified to go #2 because if I push even a tiny bit, it pokes out more. My OB says once the baby moves up, (I'm 15 weeks now, first pregnancy) things will go back to their normal place, but for now, I am so so uncomfortable :( I'm taking antibiotics and hope it clears up soon. Has anyone else been through this?
