C.P.
I drank a ton of water and was actually told to go to the bathroom because I had too much water in my blatter!! Such a releif!!!
I think I felt her move around 5.5 or 6 months. The movements were very very small at first (I first felt it while sleepping on my tummy... she didn't like it).
Enjoy it and get as much sleep as you possibly can and see every movie you want to see and read every book you want to read over the next 4 months!
