Why me?

Today, I went to my OBGYN because Provera didn't help me start my period (it’s been 132 days since my last period) and he gave me Yaz; the birth control pill. He did say that if this didn't help get my period started, they would do more exams and blood work to see if I have PCOS. I'm really worried. My husband is leaving in July to Japan and we really want to get pregnant before he leaves. I just hope this works. Has anyone else used Yaz? Or if you have PCOS, any information helps in general.
