I had an OB appointment today - I am officially 16w 5d and everything looks great. Baby was moving around a lot and everything measured in the normal range. I am still feeling really good. I did have a pretty bad headache yesterday, so my doctor reminded me again how important it is to drink enough water. Jan yelled at me that I wasn't drinking enough, but I swear I'm trying! It's become a hot summer after all - YUCK!
