Hello everyone, I'm really struggling with my bladder, it's been 39.3 for hours. I have to run to the bathroom every few minutes and feel like there's a sharp pain or a pull in my stomach. It's hard to walk around. I was hospitalized with pyelonephritis, they prescribed antibiotics... Could this be because my stomach has dropped so much and is causing the pain? Has anyone experienced this before? What can I do? This is my second pregnancy, my first son was born at 37.5 weeks without any problems.
