Lili Reinhart opened up about how fearful she was that infertility was a possibility before she was diagnosed with endometriosis. In an essay for Elle magazine published on Thursday, March 12, Reinhart, 29, opened up about a series of medical tests and treatments she went through to get answers about the chronic bladder pain she endured. "During one session, my pelvic floor therapist asked me if I had ever considered endometriosis as a cause of my symptoms. None of the eight or so doctors I had seen before her had mentioned it," she wrote.
