Hello, I am 17 years old and have not had a period in about a year. I have always had irregular periods, but there has been a complete loss (I have not had sex). I have also gained weight around my midsection and currently struggling to deal with that and an increase of body hair. Is it likely that I have polycystic ovary syndrome (PCOS)? If this is true, what medications would I likely be prescribed? Will this affect my ability to have children later? Thank you!
