For the last few days I have had the urge to urinate frequently.  No blood, no clouding, but a horrible pressure that feels like my uterus wants to fall out.  Of course, the many trips to the bathroom usually result in little to no urine but the urge continues.  I thought maybe a bladder infection but there is no burning, blood, clouding etc.  I really just feels like everything is cramping and wants to come out.
