PCOS-Polycystic ovary syndrome

Im 20 years old and I just recently got diagnosed with PCOS. She told me because I haven’t had my period in 183 days and that I why i had cyst all over my ovaries and will experience less hair and acne on my face with the meds and the birth controls I’m happy that I basically won’t have my period “anymore” sort of, she told me that my period won’t really come back it’s a maybe chance because my wall doesn’t want to like open or go back to “normal” and that my chances of getting pregnant were very very low right now and that I needed to take pills if I ever wanted kids and that I’m infertile. Has a anyone else experienced anything else with PCOS or taking pills for it? Any advice for someone dealing with PCOS?

What should I expect from major things the next few years?

Will my cyst grow bigger?
