Should I trust the Digital OPK?

Yes, I know I should trust the results.  MY SMILEY face came one day early today!  I have a positive OPK.  Month 2 attempt.  I know, it's really month 28.  But, it's sounds more positive to begin a new count.  This is what my RE does...so, why shouldn't I?  Right?  It's sad that when you have a miscarriage, you go back to Month 1.  "Give it another six months-we'll see you in May '09."  

So, the Full moon must be working tonight.
