Are there long-term side effects after taking Accutane? Specifically infertility or PCOS?

My dermatologist recommended that I take Accutane for my mild, stubborn acne. She reassured me that as long as I don't get pregnant while I'm on it, I should be fine. After a few hours of researching, I stumbled upon a forum of people who believe it caused their PCOS and other long-term health issues (supposedly it was a form of chemotherapy in the 80's?) . I really want to know the truth about this; my husband & I want to have kids within the next 2 years and I am scared of becoming infertile.
