i would sujest going to a cyropractor that specailizes in working with pregnant women. i did that when i was pregnant with my second child and it realy helped and it also made my labor shorter. also a body pillow is a big help and if you can get your hubby to massage your back it might make you sleep better at night. Hope somthing works for you i know it can get realy tiring not getting enough sleep and if your to tired you might have a longer labor and thats no fun. exercise is good to as long as you have no complications.
