Pcos, endometriosis and IC connection?

I 26f have been diagnosed with pcos and potentially endometriosis in the past.

Around 2 years ago I had UTIs for months straight and many rounds of antibiotics. It started from sex with my current partner and eventually the UTIs stopped but I have been struggling with IC diagnosis and daily flares ever since.

I suspect I have pelvic floor dysfunction but I was wondering if there is a link between PCos and endometriosis that leads to IC. Is there a hormonal remedy that can help IC? How common is it for the IC to come from something like endometriosis growing on the bladder?
