Diagnosed with PCOS

Hello, I am 17 years old and I have basically just gotten diagnosed with PCOS. They said I had to go to a GYN to fully see if that’s what I have, but my normal doctor said that I do have high testosterone levels, and PCOS runs in my family, so it could be the start of me having PCOS. My question to you guys is that I do not know much about PCOS, and I’m worried that I’ll never to be able to have my own kids in the future. I was just thinking that maybe you guys could share some of your stories with me or help explain a little better about what PCOS is.
