HI, I also have trouble sleeping at night now with my second pregnancy, 20 wks. It is very frustrating and I just try to relax about it and read some books until I can sleep again. i want to tell you that with my first pregnancy I was able to stop my back pain with prenatal yoga once a week. If I didn't go for a week, my back hurt, but if I went I was fine. Then you can do come of the exercises at home too. A little bit can go a long way.
