21 weeks pregnant!

Today I had a doctor's appointment. For the second time I was asked if I've been eating since I have only gained 2 1/2 pounds since getting pregnant. Of course, I have been eating. I'm not sure why I haven't gained because I certainly look and feel bigger. They also gave me that nasty drink for the gestational diabetes test. Hopefully I don't fail it this time like I did with Brayden and have to take the three hour test. Luckily, I didn't have GD with Brayden but the test was just annoying/long. Sleep is becoming quite difficult. My hips/lower half like lock up on me and I'm almost creaky when I try to move. :( I know that isn't going to get any better!
