Cramp, cramp, crampy...

I am so crampy.  What does this mean?  When I was crampy on Wednesday, I thought good, impending ovulation.  When I was crampy yesterday, I thought, of course, today was the IUI and I am (hopefully) ovulating.  I woke up this morning without any cramps and thought good, I must have ovulated yesterday, maybe we timed it just right this time.  

But soon after getting up, the cramps quickly returned and by this afternoon they were pretty bad again.  I don't remember this from last time.  I need to go back and reread my posts from last time.  Or maybe I should just chill out and not try to analyze every cramp, sore boob, and feeling of nausea.  Easier said than done.
