I need some input PLEASE! I'm so confused!

I haven't had a period since April 18th. I have gotten a bunch of BFNs. The doctor gave me some Prometrium to induce my period on June 2nd, I finished my last dose on June 6th. I thought I was going to finally start my period last Thursday(June 12) because I was cramping, sore boobs, and spotting. But then on Friday I didn't spot or anything. I was so disappoint. I just want to start my period, so I can start another round of Clomid. Hubby & I have been TTC since march 2013 with no luck @ all. Both of testing has all came back normal. So I'm so confused with what's going on with my body. Usually my period are pretty regular, I've never been this late. I have also been clinically diagnosed with PCOS.
