the best kind of birthday present

So remember when I said we were taking a break (and no take backs)?  Idles threats such as that cannot stop me from calculating the ETA of ovulation.  Based on past months following a clomid month I have had a 29-30 day cycle.  This puts the big event on my birthday!  I'm trying so hard not to get my hopes up or make any kind of expectations for what this month may hold, but I can't help but wonder if maybe it's a sign.  To further make my case the last day of the cycle would be on my nephew's baptism when my family would be mingling with my husband's family and so on and so on, my mind makes plans for the big WHAT IF!
I've made plans for how awesome it would be to announce we're pregnant to our families too many times to count.  Most recently Thanksgiving, then Christmas, then New Year's, then my birthday....  I feel powerless to stop this cycle of disappointment.  It seems that my rational thinking goes out the window (listen I was a math major I KNOW how to read trends).  I guess it's just a testament to how much I want a baby or how out of control my hormones are or most likely both!
My sister and I love the movie (animated film) Anastasia.  There's this quote by this bat name Bartok that think pretty much sums up what's about to happen -
You're on your own, sir! This can only end in tears!
