I'm starting to understand what people are talking about as far as being uncomfortable during the third trimester. I have started having lower abdominal cramping and tightening (maybe Braxton-Hicks contractions) after walking for a little bit. None when I'm sitting comfortably, and I feel better after resting. I think it's due to the size of my belly. I ordered a maternity support belt and can't wait until it arrives. I really hope it helps. Also, I'm increasingly uncomfortable at night. I have a whole set up with the maternity wedge and body pillow, and when I wake up uncomfortable, I switch it to the other side and roll over. This is several times a night. Plus sometimes I wake up with reflux or feeling too hot. However, I know that my getting bigger is so that the baby can get bigger, and that's good for him. So big, huge belly, here I come!
