I'm also hitting 26 weeks. Only 2 more weeks and I'll be entering my third trimester. It's hard to believe. We went to the doc today and she is very pleased with everything. Baby Girl BH's heart rate was at 135 and the doctor is not at all worried about my weight (phew!).
These days I am definitely living in an almost constant state of heartburn. I also had my first bout with swelling while I was facilitating a program for work in Tennessee. It was more standing than I am used to and I had one heckuva left cankle. I definitely have a greater appreciation for pregnant women who have jobs that require them to be on their feet. Other than that, I'm not suffering from much in the symptom department. Yay me!
