PCOS and period

Grayson • 20.. Type 1 diabetic. PCOS.
So I started on birth control for a month and then quit because it was just not working on me. It gave me the worst side effects. I had my period for 2 weeks straight and that was January 23 and stopped on February 3rd. Haven't had a period since. Just recently got diagnosed with pcos. Would pcos be reason I'm not having my period?
