Trying to hard??

Hi everyone im new to glow but hoping it works for me. My dh and i have been ttc now for almost 2 years. We had some luck and got real excited last November. But i miss carried in my 8th week. If that wasnt disappointing enough when we decided to keep trying (and believe me we have tried everything) nothing has happened. I closely monitor my ovulation cyles and we bd everyday during that time but still every month af comes. Im slowly losing hope and am wondering if we r trying to hard. When it happened before i wasnt monitoring ovulation or anything so now that i am i guess i expected results. I dunno... any advice??
