Just wasn't my mth.. Why am I taking it so hard?

Well this was my husband and I first mth ttc and today AF came... From the First day of my last period I tried to do everything right by not smoking, drinking and started my vitamins. I tracked my OV we did it when it was time and yet this month did not work out for us.. It was soooo devastating and heart breaking when AF came today I can't stop crying =( .. My husband keeps being positive and saying we will keep trying but the waiting and trying kills me... I just wanted to know how you guys deal with disappointment and stay positive will ttc? (just need some words of encouragement)
