PCOS ?

Hey ladies, so for those of you who are diagnosed with PCOS how did you find out? Did you have any signs of it before a doctor confirmed it? I scheduled an appointment for 8/10 with a primary doctor to mention these signs & concerns to them but I’m unsure on how to word everything. Basically my periods are regular for the most part but I’ve been struggling to conceive, over the years I’ve had random excessive weight gain, abnormal hair growth (not like bad bad but definitely noticeable on my neck, chin, jawline & collar bone), I have had a few early miscarriages over the years & overall my hormones feel “off”. I also went to the hospital a couple weeks ago & my blood sugar was like 129mg which I was told is high & could be a sign of diabetes. I’m just wondering what tests you guys had done & how has your journey been? I’m trying for my rainbow baby & really just want a happy ending. I’ve changed my diet I cut out excessive sugars, high sodium & fast & fatty foods, upped my water intake & have begun to take vitamin D, B6 & iron supplements so I’m overall making a change but I want to see the doctor to have tests ran. Do they do ultrasounds for PCOS?
