the "stims" have arrived

I have anticipated this day for the last month.  My first round of injectable medications arrived today in the mail.  I was very excited, it seemed surreal that it is almost time for action.  I am now just waiting on AF to show her ugly face and our journey on cycle #1 IUI begins.  Along with this comes tears, I have cried several times today already and its still before lunch.  I know that I have this flood of emotion because of the anticipation of what the future could hold for my DH and I.  Our baseline appt should be this weekend or Monday at the latest.
