Is it EVER going to happen!

I want so badly to be pregnant. My husband and I have been trying near 9 months now. We've had a lot of big life changes the last few months. My husband is about to graduate from the police academy and all I wanted was to be able to gift him the gift of being pregnant when he graduates. I had it all planned how I wanted to tell him. I thought I'd definitely be pregnant by the time he graduates next month, but now I have little hope. My period is prejected to start in 5 days. I'm not having any symptoms of being pregnant so I don't think I am. We've tried so hard the last two cycles. It's beyond discouraging.
