How much water are you drinking in pregnancy?

I feel like I drink *so* much, but haven't kept track until the past few days. Today, I have drank 5 large glasses of water by now (1:30). Also had a cup of OJ. I'll probably have 3-4 more glasses this afternoon and then a few glasses this evening (plus milk). I'm not sure what this comes out to in terms of oz. though because I'm not drinking out of a nalgene or water bottle.
