Any advice/thoughts?

My last gyn check up and pap, it was brought to my attention for the second time that I have some signs of PCOS. Ever since I was told that, and I researched it more, I have been very worried about being infertile. 
I have a scheduled ultrasound to check my ovaries here in a few weeks. It's all I think about all day long. I've never wanted anything more than to get pregnant. My boyfriend of 1-1/2 years and I both graduated from college recently and have full time jobs. Because I'm having my ultrasound, I have to be off birth control. We have talked, and agree that if we were to get pregnant it would be okay, so we have been having unprotected sex. 
I'm worried that if I don't start trying to get pregnant now, it might not happen. Any advice/thoughts?
