PCOS symptom?

My husband and I have been TTC for about 6 months. After a lot of doctor visits they diagnosed me with Polysystic ovarian syndrome. My Dr wants to start me on a fertility medication day 5 of my cycle and check me out day 9 to see if it helps. Well, I haven't had a period since May 10th. I'm NOT PREGNANT but my period hasn't come yet I suffer the symptoms: major cramping, extreme bloating, back pain, STARVING ALL THE TIME, and massive weight gain. Usually around my period I gain weight but after its over I almost instantly lose it. Sometimes my periods are like that. Sometimes I'll go 3-6 months without one yet I still endure the pain. Is this a common thing for PCOS? Any recommendations?
