PCOS?

I am almost 25 and I have always had irregular periods, but this time I haven't had one since the beginning of January.. I have been searching the web for possible reasons because I can't go to a doctor. I have no insurance and I can't get medicaid. The closest thing that I have found for my symptoms is PCOS. I have every sign.. For those that have it, what do you feel like? How does it feel? Can you tell you have cysts? Is it manageable without going to the doctor? I am so lost and so upset. I'm afraid I will never be able to have a baby, I'm scared. I don't know what to do. Please any input is greatly appreciated. ❤
