When you least expect it... It'll happen...

Kristy • After ttc for 9 months, we are finally pregnant. 😊 Due April 21, 2016. 💕
Everyone says when you least expect it it'll happen and you'll finally get pregnant... How do you make yourself stop expecting it? I just dont understand how ppl do it... And then people say to be positive. But i feel like every month i always think, " this will be my month," and it never is... How do you make yourself stop trying and not expect it?
