Does anyone have this problem?

Hi everyone, my doctors are not in agreement with each other on what this could be, pelvic issues or IC. I’m wondering if anyone here can hold it for a 2-3 hours, but when they go, like 15 mins later the urge creeps back and it’s very uncomfortable. I find the most discomfort right after I go. Does this sound like IC or more pelvic? Does anyone struggle with this? Looking for support.
