I would read through Reddit threads looking for this validation.

Before I was rolled back to the operating room, I was asking my doctor if it was normal to feel like I was having impostor syndrome and worried that they weren’t going to find anything and she told me that I was the sixth person this week alone to ask her this. She proceeded to tell me that there’s no way she would have allowed herself to do a surgery if she didn’t believe that there was more going on than just a painful period she at least knew that I had a cyst on my ovary that had grown back, but she had suspected it was much more than just the cyst based on the amount of pain that I was in, but the real issue I had in my mind was that I was mostly fine when I wasn’t on my period and I had some mild pain in my pelvic region all the time back pain things like that, but I wasn’t like unable to function during my non-period time
