What is the best way to get diagnosed with diastasis recti?

I have digestive issues, feel as though my abdomen is not supported(feeling like you are getting squished), urinary incontinence(with coughing, sneezing, and some exercise). I have aches and pains that seem to be what distracts the Drs as when I ask if it could be DR they then tell me its not a painful issue. The pains I feel completely seem like muscle tearing. It is very hard to get through an assessment when the Dr shuts you down after reading a symptom you have even when not related to your visit.
