both! I retained masses of water when pg with DD, but not so much this pregnancy. Hers was a summer pregnancy though and this one is winter. Anyway, I sweated bucket loads for a week solid after DD was born. I had lost 20kgs (44 pounds) by the time she was a week old.
PIE - kinda mixed results... laying on my back is super painful but when DH gotta good grib and pulled it REALLY helped, but then he couldnt let go cuz it's instantly hurt....cue really UNfrisky awkward man-handling of me to roll off the bed together, while still applying traction, until i could get feet on the floor due to darn leg cramps haha yep, pregnancy ROCKS.
