Sad and trying to hide it...

We've been ttc for a few months now and it hasn't happened yet.... I know it can take time.  It is just so frustrating because so many around me have these oopsie pregnancy stories and we are actually trying!  It's hard on me and I try to not let it show because everyone is so encouraging and full of positivity.  I try to stay positive but sometimes I've just got to let it out!
