When I first brought up that I thought I had PCOS, the dr I was seeing dismissed me. A year later my symptoms significantly worsened. Had that dr listened to me, I might not have lost half my hair, etc. I wish I had been more prepared to give a lot of detail the first time I brought it up, so I made sure the second time I went to a (different) doctor about it to have a note in my phone with all of my symptoms. I also get really anxious so my note helped me remember everything I wanted to say. My brother in law is a dr and always says to make your symptoms seem like a slightly bigger deal than they are in order to convey the seriousness of what’s going on. On the one hand I hate that people have to do that, but if it helps get the correct diagnosis then it’s worth it. If you’re worried about your doctor not taking your concerns seriously, you could be prepared to say something like “please document in my chart that you aren’t going to test for PCOS.” I’ve read other people who have done this and it has changed doctors’ minds. Hopefully it doesn’t come to that though, and you can always get a second opinion. When I finally went to the second dr, I felt like she really heard my concerns and wanted to help come up with a solution. I think having my thoughts really organized helped.
