Not peeing as much even though drinking more?

The past few nights have been great sleep-wise, in that I've been getting up way less the usual to use the bathroom.  However, I've been drinking more than ever as I've been super thirsty all the time!  It doesn't hurt when I pee, I don't feel backed up or nauseous, no back pain...just less pee even though I feel like I'm drinking more.  Any one with any ideas?  Similar situations?  I'm not really worried as nothing hurts/looks off.  It's just odd to me.
