Pcos?

My doctor recently told me I had pcos although I’m not very certain she’s right because it was more of a “remember you have it” like no I don’t remember because no one told me, what exactly are the symptoms if there is any of having it? And how bad can it mess up your fertility? I want a baby so bad and literally it has been on my mind ever since she said that. I don’t have insurance anymore to go forsure check, although I’m young (18) I still want to be able to have children in like 5 years and I don’t want this to ruin it for me.
