Bladder sling

So I had a bladder sling put in on March 18, voided some in my own after the catheter was removed then need to start using individual catheters. Went back to the doctor & she manually pulled on the sling to adjust it some, no luck. Went back in for surgery on a fees weeks later & had a string on the sling cut to release tension & here I am almost 2 months post surgery still not going on my own. Saw the doctor today was prescribed flomax & estrogen cream to hopefully help me start to go on my own.

Doctor is stumped as to why I am not going on my own still….any thoughts? Hate to go back under again.
